N=2 quiver gauge theories on A-type ALE spaces
Ugo Bruzzo, Francesco Sala, Richard J. Szabo
We survey and compare recent approaches to the computation of the partition functions and correlators of chiral BPS observables in gauge theories on ALE spaces base…

Instantons and framed sheaves on Kähler Deligne-Mumford stacks
Philippe Eyssidieux, Francesco Sala
We provide stacky generalizations of classical gauge-theoretic results inspired by Donaldson, the Uhlenbeck-Yau theorem and variants due to Bando and his collaborators. Moreover, w…

Representations of the Heisenberg algebra and moduli spaces of framed sheaves
Francesco Sala, Pietro Tortella
We give a `geometrical' construction of an action of a Heisenberg algebra on the homology of the moduli spaces of torsion free sheaves on a complex smooth connected projective surf…
