Abstract We study the algebra of Wilson line operators 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 ). https://www.cosmeticssquadets.shop/product-category/tools/
