In this talk, we will discuss aspects of non-abelian gauge theories in two dimensions with (0,2) supersymmetry. In particular, we will focus on the geometric phases of these gauge theories, i.e. their Higgs branches. Using geometric relations and GLSM phase structures, we will explore and discuss various dualities between these gauge theories, such as dualities that are analogous to four-dimensional Seiberg dualities. We will test these dualities by computing the elliptic genus of these dual theories; this also provides a tool of studying dynamical supersymmetry breaking in these theories.
