Whitham Deformations and Tau Functions in<i>N</i>= 2 Supersymmetric Gauge Theories
Whitham Deformations and Tau Functions in<i>N</i>= 2 Supersymmetric Gauge Theories
We review new aspects of integrable systems discovered recently in N=2 supersymmetric gauge theories and their topologically twisted versions. The main topics are (i) an explicit construction of Whitham deformations of the Seiberg-Witten curves for classical gauge groups, (ii) its application to contact terms in the u-plane integral of topologically …
