Event Details

In this talk we will discuss various recent developments in (0,2) theories in two dimensions. We will start with a brief introduction to the background knowledge of (0,2) gauge theories, then moving on to analyzing dualities between these theories by studying their Higgs branch geometries. In this context, we obtain understandings of phenomenons such as abelian-nonabelian duality, (2,2) Seiberg duality and Gadde-Gukov-Putrov triality. We will then discuss general computations of chiral spectra of (0,2) nonlinear sigma models, with an eye towards verifying Gadde-Gukov-Putrov triality. Finally, we will apply supersymmetric localization to (0,2) gauge theories and obtain exact correlation functions.
