Line defect Schur indices, Verlinde algebras and U(1) r fixed points
Abstract Given an N=2 $$ \mathcal{N}=2 $$ superconformal field theory, we reconsider the Schur index ℐ L (q) in the presence of a half line defect L. Recently Cordova-Gaiotto-Shao found that ℐ L (q) admits an expansion in terms of characters of the chiral algebra A $$ \mathcal{A} $$ introduced by Be...
