E11 and Generalised Space-time
📍 London
Peter West
(King's College)
Abstract:
It has been conjectured that the fundamental theory of strings and branes has an \(E_{11}\) symmetry. I will explain how this conjecture leads to a generalized space-time, which is automatically equipped with its own geometry, as well as equations of motion for the fields that live on this generalized space-time.

Higher Gauge Theory and M-Theory
Christian Saemann
(Edinburgh)
Abstract:
Higher Gauge Theory is a categorical way of thinking about parallel transport
of extended objects. Such parallel transport appears naturally within string
and M-theory. In particular, the six-dimensional maximally superconformal
theory or at least self-dual strings in four dimensions should be captured by
Higher Gauge Theory. I will review some of my recent work in this area,
including how M2-brane models fit into the picture, how twistor geometry can
yield field equations containing the non-abelian tensor multiplet and give
explicit higher versions of the BPST instanton and the 't Hooft-Polyakov
monopole. If time permits, I will also talk a bit about a higher version of
the IKKT matrix model.
