An elliptic Virasoro symmetry in 6d
Fabrizio Nieri
We define an elliptic deformation of the Virasoro algebra. We argue that the Nekrasov partition function reproduces the chiral blocks of this alge…

Factorisation and holomorphic blocks in 4d
Fabrizio Nieri, Sara Pasquetti
We study N=1 theories on Hermitian manifolds of the form M^4=S^1xM^3 with M^3 a U(1) fibration over S^2, and their 3d N=2 reductions. These manifolds admit an Heegaard-like decompo…
