Dolbeault Virasoro algebra and M5 branes

CMSA, 20 Garden St, G10 20 Garden Street, Cambridge

The worldvolume theory on a stack of M5 branes in M-theory is superconformal. We propose a conjecture that in the holomorphic twist of the theory on a stack of M5 […]

Scattering Amplitude from a Twistor Point of View

CMSA, 20 Garden St, G10 20 Garden Street, Cambridge

Scattering amplitude is a key quantity in quantum field theory. Although challenging to compute at higher loops and for large particle numbers, physicists have developed various tools to gain a […]

Khovanov skein lasagna modules and exotica

Science Center 507 1 Oxford Street, Cambridge

The Khovanov skein lasagna module S(X;L) is a smooth invariant of a 4-manifold X with link L in its boundary. In this talk I will outline the construction of Khovanov […]
