Title: Little String Instanton Partition Functions and Scalar Propagators
Date (JST): Mon, Mar 06, 2023, 16:00 - 17:30
Place: Hybrid
Abstract: I will discuss a class of Little String Theories whose low energy descriptions are supersymmetric gauge theories on the omega-background with gauge group U(N) and matter in the adjoint representation. The instanton partition function can be written in term of Kronecker-Eisenstein series and interpreted both physically and geometrically; leading to a rewriting of the partition function in term of free scalar propagators on the torus. Furthermore, using the formulation of the partition function in terms of the Kronecker-Eisenstein series, I will argue for new recursive structures which relate higher instanton contributions to products of lower ones.
