Hans Jockers: Wilson Loop Algebras and Quantum K-Theory

Abstract: In this talk we review certain aspects of Wilson line operators in 3d N=2 supersymmetric gauge theories with a Higgs branch that is geometrically described by complex Grassmannians. We discuss the relationship between Wilson loop algebras of the gauge theory and the quantum K-theoretic ring of Schubert structure sheaves of the complex Grassmannians.
