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…
