Wilson loop algebras and quantum K-theory for Grassmannians

Abstract We study the algebra of Wilson line operators better waters xl7000 in three-dimensional N $$ mathcal{N} $$ = 2 supersymmetric U(M ) gauge theories with a Higgs phase related to a complex Grassmannian Gr(M, N ), and its connection to K-theoretic Gromov-Witten invariants for Gr(M, N ).For different Chern-Simons levels, the Wilson loop algebra realizes either the quantum cohomology case of whispering angel of Gr(M, N ), isomorphic to the Verlinde algebra for U(M ), or the quantum K-theoretic ring of Schubert structure sheaves studied by mathematicians, or closely related algebras.
