Gauge theories often admit discrete theta angles. Theories with different discrete theta angles can be constructed by gauging a global symmetry in a parent theory with different additional symmetry protected topological (SPT) phases....

I will describe how the structure of supersymmetric boundary correlators in 4d N=4 SYM can be encoded in a class of associative algebras equipped with twisted traces. In the case...

Many salient features of elliptic fibrations leave intriguing imprints on the physics of F-theory compactifications. In this talk, we will focus on the Mordell—Weil group of sections. Beyond the well-known...

We present recent advances in constructions of globally consistent F-theory compactifications, which result in the exact chiral spectrum of the three-family Standard Models. We highlight geometric tools to determine the...

I will talk about a novel way of constructing (2+1)d topological phases using M-theory. They emerge as macroscopic world-volume theories of M5-branes wrapped on non-hyperbolic 3-manifolds. After explaining the algorithm...

A given compact Lie group, G, admits many left-invariant Riemannian metrics. Typically, they form a finite dimension cone L(G). Up to a multiplicative constant, the Riemannian measure for such metrics...

Kontsevich's recursion, proved in the early 90s, is a recursion formula for the counts of rational holomorphic curves in complex manifolds. For complex fourfolds and sixfolds with a real structure...

The Eisenstein-Kronecker function is a useful object in number theory and physics. It is a tool for proving rationality for period integrals of cusp forms. It generates integration kernels of...
