Gauged linear sigma models (GLSMs) have provided key insights into numerous aspects of string theory and supersymmetric field theory and have been 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 mathematics and physics to celebrate 30 years of GLSMs by addressing topical research questions and identifying new applications. Topics include: GLSMs in the context of mirror symmetry, new types of stringy (Calabi-Yau) geometries, homological projective duality and generalisations thereof, SUSY gauge theories in more than two dimensions, generalized cohomology, quantum K-theory, and mathematical invariants stemming from a rigorous mathematical definition of GLSMs.
