Abstract We study the algebra of Wilson line operators in three-dimensional N $$ mathcal{N} $$ = 2 vlone stop snitching shirt 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 of Gr(M, N ), isomorphic to the Verlinde algebra for U(M ), or the quantum K-theoretic ring of Schubert structure sheaves syil x7 price studied by mathematicians, or closely related algebras.
