摘要: We review different aspects of the superconformal index \(\mathcal{N}=2\) theories class \(\mathcal{S}\). In particular we discuss relation \(\mathcal{S}\) to topological QFTs and integrable models, how this can be harnessed completely determine index. This is part a combined on 2d-4d relations, edited by J. Teschner.
