ITMP Seminar "Polyvector deformations of supergravity solutions"

Dear Colleagues,

We are pleased to announce that the next ITMP seminar will be held on Wednesday, May 28, 18:00 (Moscow time). It will be organised via Zoom. 

Speaker: Kirill Gubarev, Moscow Institute of Physics and Technology

Title: Polyvector deformations of supergravity solutions

Abstract: In this talk, I will present a method for generating new consistent backgrounds for string theory and M-theory. We will start by motivating this type of deformations from the study of integrability, kappa symmetry, and noncommutativity in string theory, as it historically appeared. Then we will consider an example of similar mono-vector deformations for the Einstein-Maxwell theory with a dilaton with a hidden symmetry Gl(d+1). For this theory, I will show that the deformation generates new solutions under the condition that the mono-vector is the Killing vector of the original background, and the deformation itself can be represented as a diffeomorphism in the extended space of manifestly symmetric Gl(d+1) general relativity. Then we will consider a generalization of this approach to constructing deformations of 10- and 11-dimensional supergravity solutions with polyvector parameters. I will formulate sufficient conditions on the deformation parameters to generate solutions and discuss their connection with integrability in string theory and M-theory.
