Contact isotopies in the coherent-constructible correspondence
Jishnu Bose, Harold Williams
The coherent-constructible correspondence is a realization of toric mirror symmetry in which the A-side is modeled by constructible sheaves on . This paper provides a geometri…
Canonical bases for Coulomb branches of 4d gauge theories
Sabin Cautis, Harold Williams
We construct and study a nonstandard t-structure on the derived category of equivariant coherent sheaves on the Braverman-Finkelberg-Nakajima space of triples ,…
Tamely presented morphisms and coherent pullback
Sabin Cautis, Harold Williams
We study two classes of morphisms in infinite type: tamely presented morphisms and morphisms with coherent pullback. These are generalizations of finitely presented morphisms and m…
Ind-geometric stacks
Sabin Cautis, Harold Williams
We develop the theory of ind-geometric stacks, in particular their coherent and ind-coherent sheaf theory. This provides a convenient framework for working with equivariant sheaves…
Kasteleyn operators from mirror symmetry
David Treumann, Harold Williams, Eric Zaslow
Given a consistent bipartite graph in with a complex-valued edge weighting we show the following two constructions are the same. The first is to form the Ka…
