Supersymmetry breaking and singularity in dynamical brane backgrounds

Nov. 02 - 14:30 - 2017

Kunihito Uzawa (Kwansei Gakuin University)

The supersymmetry arises in certain theories of fermions coupled to gauge fields and gravity in a spacetime of higher dimensions as well as 4 dimensions. Dynamical brane backgrounds in supergravity and string theory have mainly been studied for the class of purely bosonic solutions only, but recent developments involving time-dependent brane solution have made it clear that one can get more information by asking what happens on supersymmetric systems. In this talk, we present exact supersymmetric solutions of dynamical D-brane, M-brane backgrounds in the 10- and 11-dimensional supergravity. We also show the supersymmetry breaking, and discuss geometric features near the singularity
and the black hole horizon.
