[hep-th] Strings, Holography & Chaos Seminar February 25 12:00 CET (IPB, 2nd floor theory seminar room): Ziqi Yan

[Mihailo Čubrović]

Dear friends,

On February 25 (Wednesday) at 12:00 CET we will have a seminar by Ziqi 
Yan, in the theory seminar room (Institute of Physics Belgrade, 2nd 
floor). Ziqi will be around for three days (Mon-Wed), so if you want to 
have a chat drop me an email and I'll get you in touch. Title and 
abstract follow.

Unification of Decoupling Limits in M-Theory

Ziqi Yan, The Niels Bohr Institute, Copenhagen University

I will discuss BPS limits of M-theory that lead to U-dual webs of 
decoupled theories, whose fundamental degrees of freedom are described 
by matrix theories. The decoupling limits are organized by five 
different duality orbits of M-theory in DLCQs. Via a generalization of 
the TTbar deformation to p-branes, this leads to a classification of 
holographic constructions in string theory. I will show that 
non-Lorentzian geometric techniques play an indispensable role in this 
framework. By examining the fundamental strings in these decoupled 
theories, I will argue how (non-)Lorentzian supergravity equations of 
motion arise from the corners associated with different matrix theories.
