3d N=2 gauge theories for M2-branes at toric CY4 cones and the uplift of D6-branes
๐ London
Stefano Cremonesi
(Tel Aviv University)
Abstract:
I will review recent progress in understanding the 3d N=2
superconformal field theories which describe the low energy dynamics
of M2-branes probing toric CY_4 cones in M-theory, based on a KK
reduction of M-theory to type IIA string theory.
A key role in field theory is played by 't Hooft monopole operators,
disorder operators which encode the geometric details of the reduction.

Travelling Front of the Decaying Brane
Debashis Ghoshal
(Jawaharlal Nehru University, India)
Abstract:
Some of the perturbative vacua of open string theory are
known to be unstable. They decay to other (meta-)stable vacua. We will consider the dynamics of this relaxation process (decay). In particular, the equation that describes an inhomogeneous decay turns out to be a variant of a non-linear partial differential equation that appears in many other areas. We will point out their similarities and differences.
