Gauged Linear Sigma Models

One of the most important tools to quantitatively describe families of two-dimensional conformal field theories are gauged linear sigma models (GLSMs). As such they offer a powerful and indispensable method to study string compactifications and their phase structures from a worldsheet perspective. Over the years, the scope of GLSMs has developed much further, namely not only as a methodology to study string theories, but also to address fundamental questions of (supersymmetric) quantum field theories, in particular in two, three and four dimensions. That is to say, GLSMs have provided key insights into numerous aspects of mathematical physics, offering a bridge to various fields in mathematics such as enumerative and algebraic geometry and category theory. The aim of this workshop is to bring together experts from physics and mathematics in order to address topical research questions and to identify new applications for GLSMs.
