AGT relations for abelian quiver gauge theories on ALE spaces
Mattia Pedrini, Francesco Sala, Richard J. Szabo
We construct level one dominant representations of the affine Kac-Moody algebra on the equivariant cohomology groups of moduli spaces of rank one framed…

Framed sheaves on root stacks and supersymmetric gauge theories on ALE spaces
Ugo Bruzzo, Mattia Pedrini, Francesco Sala +1
We develop a new approach to the study of supersymmetric gauge theories on ALE spaces using the theory of framed sheaves on root toric stacks, which illuminates relations with gaug…

Framed sheaves on projective stacks
Ugo Bruzzo, Francesco Sala
Given a normal projective irreducible stack over an algebraically closed field of characteristic zero we consider framed sheaves on , i.e., pairs $(\mathca…
