Surface defects and instanton partition functions
Davide Gaiotto, Hee-Cheol Kim
We study the superconformal index of five-dimensional SCFTs and the sphere partition function of four-dimensional gauge theories with eight supercharges in the presence of co-dimen…
Defects and Quantum Seiberg-Witten Geometry
Mathew Bullimore, Hee-Cheol Kim, Peter Koroteev
We study the Nekrasov partition function of the five dimensional U(N) gauge theory with maximal supersymmetry on R^4 x S^1 in the presence of codimension two defects. The codimensi…
The Superconformal Index of the (2,0) Theory with Defects
Mathew Bullimore, Hee-Cheol Kim
We compute the supersymmetric partition function of the six-dimensional theory of type on in the presence of both codimension two and codimension…
Witten Index and Wall Crossing
Kentaro Hori, Heeyeon Kim, Piljin Yi
We compute the Witten index of one-dimensional gauged linear sigma models with at least supersymmetry. In the phase where the gauge group is broken to a finite gro…
