How many coordinates does DFT have?
- Georgios PAPADOPOULOS (Kings College London)
10:30 AM - 11:30 AM
Room: 4-3-006 - TH Conference Room I shall describe the puzzles and challenges that rise in attempting to globally patch DFT. Then I shall propose a new class of spaces, the C-spaces, which contain locally the doubled spaces and resolve some of the puzzles. I shall also explain the relation of C-spaces to generalized geometry, and describe how the 3-form flux is geometrised. Some topological aspects of the geometrisation of fluxes, in particular the relation to Whitehead towers, will be explored.

On (4+6)-dimensional SUSY vacua with non-geometric fluxes
- David Andriot (MPI, AEI Potsdam-Golm)
10:30 AM - 11:30 AM
Room: 4-3-006 - TH Conference Room In the 10-dimensional framework of beta-supergravity, we characterize (4+6)-dimensional vacua preserving supersymmetry. We rewrite Killing spinor equations with NSNS non-geometric fluxes using the language of SU(3)*SU(3) structures and Generalized Complex Geometry, in analogy to standard type II supergravities. The NSNS generalized differential operator D that appears exhibits interesting properties, among which being a Generalized Dirac operator. This formulation leads us to a general expression for the superpotential, and we successfully compare it to existing formulas in the literature.

3:30 PM - 4:00 PM
Room: 4-3-006 - TH Conference Room I will consider generalized diffeomorphisms in exceptional geometry from an algebraic point of view. By extending the U-duality algebra E_n to an infinite-dimensional Lie superalgebra of Borcherds type, the generalized Lie derivatives can be expressed in a simple way, and the expression takes the same form for any n<8. The closure of the transformations then follows from the Jacobi identity and other fundamental properties of this Borcherds superalgebra.

Consistent Scherk-Schwarz compactifications using exceptional field theory
- Emanuel Malek (LMU Munich)
10:30 AM - 11:30 AM
Room: 4-3-006 - TH Conference Room We discuss 7-dimensional maximal gauged supergravities arising from Scherk-Schwarz compactifications using exceptional field theory. We show how to map consistent compactifications of 10-dimensional type IIA theory into consistent compactifications of 10-dimensional type IIB theory and vice versa and show how this map transforms the resultant gaugings of the 7-dimensional embedding tensor. We use this map to extend the known consistent compactifications of10-dimensional type IIA theory on hyperboloidal spaces $H^{p,q}$ to compactifications of 10-dimensional type IIB theory on such $H^{p,q}$ spaces.

2:00 PM - 3:00 PM
Room: 4-3-006 - TH Conference Room We investigate exceptional generalised diffeomorphisms based on E_8(8) in a geometric setting. The transformations include gauge transformations for the dual gravity field. The surprising key result, which allows for a development of a tensor formalism, is that it is possible to define field-dependent transformations containing connection, which are covariant. We solve for the spin connection and construct a curvature tensor. A geometry for the Ehlers symmetry SL(n + 1) is sketched. Some related issues are discussed. If time allows I will also discuss solution (and relaxation) of the section condition in terms of a twistor transform in a first-quantised setting.
