Twisted Elliptic Genera of N=2 SCFTs in Two Dimensions
Toshiya Kawai
The elliptic genera of two-dimensional N=2 superconformal field theories can be twisted by the action of the integral Heisenberg group if their U(1) charges are fractional. The bas…

Abelian Vortices on Nodal and Cuspidal Curves
Toshiya Kawai
We compute the Euler characteristics of the moduli spaces of abelian vortices on curves with nodal and cuspidal singularities. This generalizes our previous work where only nodes w…
