We identify the representations of these algebra's\, which make up the cla ssical supergravity spectra and argue for the presence of\nthese spectrum generating algebra's in the classical string/M-theory.

It forms an involution that preserves metric and hyperKahler s tructure of the instanton moduli spaces. It can be put to practical use by observing that charge 1 instantons are mapped to an abelian problem\, and that non-compact directions (infinite periods) lead to dimensional reduct ion on the dual torus. \nIntricate relations have been found\, partly base d on numerical studies and partly on analytic results\, whose usefulness m ay extend beyond gauge theory applications.

We will briefly review how such a SCFT arises from th e \ngauge theory of open strings on the D-brane system\, leading to a targ et space which is an orbifold. The resulting twisted sectors lead to a dif ferent 'effective string' picture than initially proposed and removes earl ier discrepancies in Hawking radiation rates between brane computations an d supergravity. We will discuss the issue of marginal decay and fragmentat ion of the five-dimensional black holes in the absence of moduli. We will discuss how to construct true bound states (stable black holes)\, both in terms of supergravity and gauge theory. The gauge theory corresponding to the stable D1/D5 system turns out to be non-commutative.\n\nhttp://indico. cern.ch/conferenceDisplay.py?confId=a033253 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033253 END:VEVENT BEGIN:VEVENT SUMMARY:Issues in AdS/CFT\n DTSTART;VALUE=DATE-TIME:19991123T130000Z DTEND;VALUE=DATE-TIME:19991123T153000Z DTSTAMP;VALUE=DATE-TIME:20130519T222439Z UID:indico-event-a033254@cern.ch DESCRIPTION:We use the AdS/CFT correspondence to calculate two and three p oint functions for a class of chiral operators\, including the primary one s\, in d = 3\, N = 8\; d = 6\, N = (2\,0) and d = 4\, N = 4 superconformal field theories at large N.

In particular\, they produce SU(3)xSU(2)xU(1) gauge group\, with th ree generations of quarks and leptons. I will also discuss how these confi gurations can be embedded in compact models preserving N=1 supersymmetry o r breaking it in a hidden sector. These models provide explicit string the ory realisations of the brane-world \nscenario\, with the Standard Model s ector embedded in a set of D3-branes. The construction of the models follo ws a bottom-up philosophy: In a first step one scans large families of sin gularities\, and singles out those leading to phenomenological promising f ield theories. In a second step\, one embeds such local structures in a gl obal model\, namely a compact space. Many phenomenological issues\, like g auge coupling unification\, proton stability\, etc\, are controlled by the structure of the singularity\, and so are quite independent on the global structure of the compactification.\n\nhttp://indico.cern.ch/conferenceDis play.py?confId=a033267 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033267 END:VEVENT BEGIN:VEVENT SUMMARY:Open strings in the background of NS 5-branes\n DTSTART;VALUE=DATE-TIME:20000606T120000Z DTEND;VALUE=DATE-TIME:20000606T121500Z DTSTAMP;VALUE=DATE-TIME:20130519T222439Z UID:indico-event-a033268@cern.ch DESCRIPTION:We study the dynamics of D-branes in the near-horizon geometry of NS fivebranes. This leads to a holographically dual description of the physics of D-branes ending on and/or intersecting NS5-branes. We use it t o verify some properties of such D-branes\, which were deduced indirectly in the past\, and discuss some instabilities of non-supersymmetric brane c onfigurations.

The cosmological constant rece ives contributions only from the vacuum energy of the bulk supergravity fi elds\, but not from the vacuum energy of the brane fields. The latter is a bsorbed in a warp factor. Supersymmetry breaking on the brane at the TeV s cale implies supersymmetry breaking in the bulk at the micrometer scale. T his produces a tiny cosmological constant that agrees with experiment with in a few orders of magnitude. Our argument predicts gravitinos and dilaton s with masses of order 10-3 - 10-2 eV. They should be observable in short- distance tests of Einstein Gravity.\n\nhttp://indico.cern.ch/conferenceDis play.py?confId=a033265 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033265 END:VEVENT BEGIN:VEVENT SUMMARY:Space-time non-commutativity in string theory DTSTART;VALUE=DATE-TIME:20000704T120000Z DTEND;VALUE=DATE-TIME:20000704T143000Z DTSTAMP;VALUE=DATE-TIME:20130519T222439Z UID:indico-event-a033270@cern.ch DESCRIPTION:http://indico.cern.ch/conferenceDisplay.py?confId=a033270 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033270 END:VEVENT BEGIN:VEVENT SUMMARY:Aspects of the BTZ black hole\n DTSTART;VALUE=DATE-TIME:20000711T120000Z DTEND;VALUE=DATE-TIME:20000711T143000Z DTSTAMP;VALUE=DATE-TIME:20130519T222439Z UID:indico-event-a033271@cern.ch DESCRIPTION:We show how a theorem of Sullivan provides a precise mathemati cal statement of a three-dimensional holographic principle.

Monopoles of the maximal Abelian gauge s ubgroup represent the low-energy degrees of freedom only in a restricted n umber of vacua. In more typical vacua the constituents of the monopole\, d ual quarks\, describe the low-energy physics. Their condensation induces c onfinement and dynamical symmetry breaking simultaneously. In another clas s of vacua\, however\, the low-energy physics is described by non-trivial interacting superconformal theories. For larger numbers of flavour\, there are also vacua in the free magnetic phase.\n\nhttp://indico.cern.ch/confe renceDisplay.py?confId=a033279 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033279 END:VEVENT BEGIN:VEVENT SUMMARY:Post-Riemannian merger of Yang-Mills interactions with gravity DTSTART;VALUE=DATE-TIME:20000831T120000Z DTEND;VALUE=DATE-TIME:20000831T121500Z DTSTAMP;VALUE=DATE-TIME:20130519T222439Z UID:indico-event-a033278@cern.ch DESCRIPTION:We show that a space-time with torsion and non-metricity\, obt ained as a deformation of a Riemannian space-time\, accommodates an intern al symmetry structure of the Yang-Mills prototype in such a way that the i nternal symmetry becomes an integral part of the space-time itself. In par ticular\, the space-time structural identities remain invariant with respe ct to internal gauge transformations. The construction encrusts the intern al degrees of freedom in space-time in such a way as to merge the gauging of these internal degrees of freedom with the frame geometrical gauges of space-time. In a Weyl Cartan space-time the theory regains the original co nceptual structure of Einstein's equations\, in which ``matter'' sources o n the r.h.s. determine on the l.h.s the geometry of space-time and the fie lds it induces. In a genuine post-Riemannian space-time the connection at the internal symmetry sector becomes scale-dependent\; the presence of an Abelian component in it gives rise to new contributions of gravitational m agnitude in the interaction between the Yang-Mills field and gravity. The merger of space-time with internal degrees of freedom\, which we propose h ere\, is not constrained by the usual Coleman-Mandula considerations.\n\nh ttp://indico.cern.ch/conferenceDisplay.py?confId=a033278 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033278 END:VEVENT BEGIN:VEVENT SUMMARY:Green-Schwarz action in AdS5 x s5 in light-cone gauge DTSTART;VALUE=DATE-TIME:20000905T120000Z DTEND;VALUE=DATE-TIME:20000905T121500Z DTSTAMP;VALUE=DATE-TIME:20130519T222439Z UID:indico-event-a033280@cern.ch DESCRIPTION:http://indico.cern.ch/conferenceDisplay.py?confId=a033280 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033280 END:VEVENT BEGIN:VEVENT SUMMARY:Review of non-commutative string theory DTSTART;VALUE=DATE-TIME:20001017T120000Z DTEND;VALUE=DATE-TIME:20001017T133000Z DTSTAMP;VALUE=DATE-TIME:20130519T222439Z UID:indico-event-a033281@cern.ch DESCRIPTION:This is the second lecture of our Tuesday series of reviews on recent theoretical theory developments.

They arise from a consistent truncation procedure which generates space -time fermions out of bosons. This procedure is extended to open string se ctors. We prove that truncation of the unique tadpole-free SO (2^13) boson ic string theory compactified on the above lattice determines the anomaly free Chan - Paton group of the Type I theory and the consistent Chan - Pat on groups of Type 0 theories. It also predicts the tension of space-fillin g D-branes in these fermionic theories. The derivation of these fermionic string properties from bosonic considerations alone points towards a dynam ical origin of the truncation process. Space-time fermions and supersymmet ries would then arise from bosonic degrees of freedom and no fermionic deg rees of freedom would be needed in a fundamental theory of quantum gravity .\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=a033297 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033297 END:VEVENT BEGIN:VEVENT SUMMARY:Derivative corrections from non-commutativity DTSTART;VALUE=DATE-TIME:20010918T120000Z DTEND;VALUE=DATE-TIME:20010918T130000Z DTSTAMP;VALUE=DATE-TIME:20130519T222439Z UID:indico-event-a033298@cern.ch DESCRIPTION:http://indico.cern.ch/conferenceDisplay.py?confId=a033298 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033298 END:VEVENT BEGIN:VEVENT SUMMARY:Derivative corrections from non-commutativity DTSTART;VALUE=DATE-TIME:20010925T120000Z DTEND;VALUE=DATE-TIME:20010925T130000Z DTSTAMP;VALUE=DATE-TIME:20130519T222439Z UID:indico-event-a033299@cern.ch DESCRIPTION:http://indico.cern.ch/conferenceDisplay.py?confId=a033299 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033299 END:VEVENT BEGIN:VEVENT SUMMARY:Flat bundles\, orientifolds and gerbes DTSTART;VALUE=DATE-TIME:20011002T120000Z DTEND;VALUE=DATE-TIME:20011002T130000Z DTSTAMP;VALUE=DATE-TIME:20130519T222439Z UID:indico-event-a033300@cern.ch DESCRIPTION:The non-perturbative gauge group of the type I string in 10 di mensions is Spin(32)/Z2.

We analyze the simple case of a Double-Trace deformation and show that in the gravity approximation i t appears as a change in the boundary condition on fields. We use a prescr iption for the action and boundary conditions that is somewhat different f rom the one usually found in the literature. We comment how this extends n aturally also to the general case of Multi-Trace deformations.\n\nhttp://i ndico.cern.ch/conferenceDisplay.py?confId=a033313 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033313 END:VEVENT BEGIN:VEVENT SUMMARY:Electric-magnetic duality in the parametrization of the SU(2) Yang -Mills field\n DTSTART;VALUE=DATE-TIME:20020319T130000Z DTEND;VALUE=DATE-TIME:20020319T140000Z DTSTAMP;VALUE=DATE-TIME:20130519T222439Z UID:indico-event-a033314@cern.ch DESCRIPTION:An explicit parametrization of the SU(2) Yang-Mills field in t erms of chiral fields (with values on a unit sphere) is proposed. These ch iral fields correspond to 'electric' and 'magnetic' degrees of freedom and enter the action in a similar way. In static configurations\, this simila rity turns into an exact duality.\n\nhttp://indico.cern.ch/conferenceDispl ay.py?confId=a033314 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033314 END:VEVENT BEGIN:VEVENT SUMMARY:Anomaly and non-planar diagrams in non-commutative gauge theories DTSTART;VALUE=DATE-TIME:20020402T120000Z DTEND;VALUE=DATE-TIME:20020402T130000Z DTSTAMP;VALUE=DATE-TIME:20130519T222439Z UID:indico-event-a033319@cern.ch DESCRIPTION:The local and global anomalies of non-commutative U(1) and U(N ) gauge theories will be studied in detail. We are specially interested in the anomalies arising from non-planar diagrams of non-commutative gauge t heories. We will show that non-commutative U(1) and U(N) with matter field s in the adjoint representation are free of chiral anomaly. As it turns ou t\, non-commutative U(1) gauge theory possesses three different currents\, only one of them leading to purely planar contributions to the anomaly. T he second current yields\, due to UV/IR mixing\, a finite anomaly arising only from non-planar diagrams. The result contains a so-called 'generalize d' non-commutative *-product of gauge fields.\n\nhttp://indico.cern.ch/con ferenceDisplay.py?confId=a033319 LOCATION:CERN SL Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033319 END:VEVENT BEGIN:VEVENT SUMMARY:Non-extremal fractional branes \n DTSTART;VALUE=DATE-TIME:20020409T120000Z DTEND;VALUE=DATE-TIME:20020409T130000Z DTSTAMP;VALUE=DATE-TIME:20130519T222439Z UID:indico-event-a033318@cern.ch DESCRIPTION:We construct and discuss non-extremal fractional D-brane solut ions of type-II string theory at the Z2 orbifold point of K3.

Short or long massive multiplets depend on the nature of the 'flat group'. These gauged supergravities cover the low-energy descri ption of the Scherk-Schwarz breaking via generalized dimensional reduction and certain string compactifications with G-fluxes turned on.

This approach has been recently generalized to four dimensional non -critical strings\, and yields fully non-perturbative results.

We study the kinematics of conformal fields in this limit in a geometric approach where the effect of the contraction can be visualized as an expansion of space-time. We discuss the two common models of space-t ime as carrier spaces for conformal fields: One is the usual Minkowski spa ce and the other is the coset of the conformal group over its maximal comp act subgroup. We show that only the latter manifold and the corresponding conformal representation theory admit a non-singular contraction limit. We also address the issue of correlation functions of conformal fields in th e pp-wave limit. We show that the (two-point) correlators have a well-defi ned contraction limit if their space-time dependence merges with the depen dence on the coordinates of the R symmetry group. This is a manifestation of the fact that in the limit the space-time and R symmetries become indis tinguishable. Our results might find applications in actual calculations o f correlation functions of composite operators in N=4 super Yang-Mills the ory.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=a033326 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033326 END:VEVENT BEGIN:VEVENT SUMMARY:Title to be announced\n DTSTART;VALUE=DATE-TIME:20020709T120000Z DTEND;VALUE=DATE-TIME:20020709T130000Z DTSTAMP;VALUE=DATE-TIME:20130519T222439Z UID:indico-event-a033325@cern.ch DESCRIPTION:http://indico.cern.ch/conferenceDisplay.py?confId=a033325 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033325 END:VEVENT BEGIN:VEVENT SUMMARY:Higher equations of motion in Liouville field theory\n DTSTART;VALUE=DATE-TIME:20020716T120000Z DTEND;VALUE=DATE-TIME:20020716T130000Z DTSTAMP;VALUE=DATE-TIME:20130519T222439Z UID:indico-event-a033327@cern.ch DESCRIPTION:I argue that in Liouville field theory an infinite series of l ocal field equations hold\, which generalize the basic equation of motion (the Liouville equation).
