High-Temperature Asymptotics of the 4d Superconfomal Index
The 4d superconformal index is a partition function (somewhat analogous to the quantum mechanical Witten index, or the 2d SCFT elliptic genus) that counts supersymmetric operators in 4d superconformal field theories. As a partition function it depends on a ``temperature'' parameter which enters the Boltzmann weights of various operators.I will discuss the rich structure in the high-temperature limit of this partition function, and present its leading and next-to-leading asymptotics. In particular, I explain that
