We are pleased to announce that the next Институт теоретической и математической физики ITMP seminar will be held on Wednesday, April 29, at 18:00. The seminar will be arranged via Zoom.
Speaker: Dr. Ilya Bakhmatov, ITMP
Topic: Polyvector deformations in supergravity and the string/M-theory dynamics
Abstract: Integrability preserving Yang-Baxter deformations of the string sigma-model have a simple supergravity description. We will review how introducing an extra bi-vector field to account for the r-matrix, one recovers the YB deformations after the simple open/closed string map. Things can be made clearer by using the formalism of double field theory, a T-duality covariant description of supergravity defined on an extended spacetime. We will discuss generalisations to the tri-vector deformations of d=11 supergravity and potential consequences for the fundamental membrane dynamics.
If you want to join the seminar please register here before 15:00, April 29:
