Abstract:	The elegant combinatorial mirror construction of Batyrev and Borisov for Calabi-Yau complete intersections in toric varieties has received much study, in part due to the availability of a tool -- Witten's gauged linear sigma model with an abelian gauge group -- to analyze the corresponding physical theories. There has been significant recent progress, starting with work of Hori and Tong in 2006, in understanding gauged linear sigma models with nonabelian gauge groups. In this talk we will explain some of this progress, and draw some implications for the study of mirror symmetry.
