DESCRIPTION:Speakers: Mark Robert Baker (University of Western Ontario)\nT
he oral presentation will consist primarily of a recently published articl
e in International Journal of Modern Physics D entitled "A connection betw
een linearized Gauss–Bonnet gravity and classical electrodynamics"\, aut
hored by MR Baker and S Kuzmin. In this article\, a connection between a w
ell known gravitational model and classical electrodynamics is derived. Gi
ven the excitement among physicists regarding the relationship between the
fundamental interactions of nature\, this should be an interesting talk f
or all audiences. A more formal abstract from the article regarding techni
cal contents within is given in the next paragraph\, however the talk will
be less technical than the contents of the article.\n\nContent abstract:
A connection between linearized Gauss–Bonnet gravity and classical elect
rodynamics is found by developing a procedure which can be used to derive
completely gauge-invariant models. The procedure involves building the mos
t general Lagrangian for a particular order of derivatives (N) and a rank
of tensor potential (M)\, then solving such that the model is completely g
auge-invariant (the Lagrangian density\, equation of motion and energy–m
omentum tensor are all gauge-invariant). In the case of N=1 order of deriv
atives and M=1 rank of tensor potential\, electrodynamics is uniquely deri
ved from the procedure. In the case of N=2 order of derivatives and M=2 ra
nk of symmetric tensor potential\, linearized Gauss–Bonnet gravity is un
iquely derived from the procedure. The natural outcome of the models for c
lassical electrodynamics and linearized Gauss–Bonnet gravity from a comm
on set of rules provides an interesting connection between two well-explor
ed physical models.\nhttps://indico.cern.ch/event/776181/contributions/334
