Bosonic and fermionic 1-form symmetries and anomaly matching

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

In this talk, I will consider bosonic and fermionic (non-invertible) 1-form symmetries in 2+1d QFTs. These are 1-form symmetries implemented by topological line operators with real spins. I will present a […]

Positive mass and rigidity theorems in Riemannian geometry

CMSA, 20 Garden St, Common Room 20 Garden Street, Cambridge

Positive mass theorem proved by Schoen-Yau, Witten, Taubes-Parker is one of the most important results in scalar curvature geometry in asymptotically flat settings. Since then several versions have been proven […]
