The ABCDEFG of Instantons and W-algebras
Christoph A. Keller, Noppadol Mekareeya, Jaewon Song +1
For arbitrary gauge groups, we check at the one-instanton level that the Nekrasov partition function of pure N=2 super Yang-Mills is equal to the norm of a certain coherent state o…
Towards a 4d/2d correspondence for Sicilian quivers
Lotte Hollands, Christoph A. Keller, Jaewon Song
We study the 4d/2d AGT correspondence between four-dimensional instanton counting and two-dimensional conformal blocks for generalized SU(2) quiver gauge theories coming from punct…
From SO/Sp instantons to W-algebra blocks
Lotte Hollands, Christoph A. Keller, Jaewon Song
We study instanton partition functions for N=2 superconformal Sp(1) and SO(4) gauge theories. We find that they agree with the corresponding U(2) instanton partitions functions onl…
Phase transitions in symmetric orbifold CFTs and universality
Christoph A. Keller
Since many thermodynamic properties of black holes are universal, the thermodynamics of their holographic duals should be universal too. We show how this universality is exhibited…
