Quarter-indices for basic ortho-symplectic corners

A bstract We study supersymmetric quarter-indices for corner configurations in 4d $$ \mathcal{N} $$ N = 4 super Yang-Mills theory with orthogonal and symplectic gauge groups. For the basic Y-junctions, we obtain exact closed-form expressions for the indices by making use of the G...
