Differential operators on the base affine space of and quantized Coulomb branches
Tom Gannon, Harold Williams
We show that the algebra of differential operators on the base affine space of is the quantized Coulomb branch of a certain 3d quiver gau…
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…
