We consider the stack of coherent algebras with proper support, a moduli problem generalizing Alexeev and Knutson's stack of branchvarieties to the case of an Artin stack. The main results are proofs of the existence of Quot and Hom spaces in greater generality than is currently known and several applications to Alexeev and Knutson's original construction: a proof that the stack of branchvarieties is always algebraic, that limits of one-dimensional families always exist, and that the connected… 

Compactified moduli of projective bundles

We present a method for compactifying stacks of $\PGL_n$-torsors (Azumaya algebras) on algebraic spaces. In particular, when the ambient space is a smooth projective surface we use our methods to

The cohomological Hall algebra of a surface and factorization cohomology

For a smooth quasi-projective surface S over complex numbers we consider the Borel-Moore homology of the stack of coherent sheaves on S with compact support and make this space into an associative

A relative stack of principal G-bundles over

TLDR
A proof that a relative moduli stack of principal G-bundles over a moduli Stack of genus g, n-pointed twisted curves is a smooth Artin stack locally of finite type with the universal family is recorded.

A Luna étale slice theorem for algebraic stacks

We prove that every algebraic stack, locally of finite type over an algebraically closed field with affine stabilizers, is etale-locally a quotient stack in a neighborhood of a point with a linearly

Cohomology and base change for algebraic stacks

We prove that cohomology and base change holds for algebraic stacks, generalizing work of Brochard in the tame case. We also show that Hom-spaces on algebraic stacks are represented by abelian cones,

Mapping stacks and categorical notions of properness

One fundamental consequence of a scheme being proper (and flat over a base) is that there is an algebraic space classifying maps from it to any other finite type scheme, and this result has been

Blt Azumaya algebras and moduli of maximal orders

We study moduli spaces of maximal orders in a ramified division algebra over the function field of a smooth projective surface. As in the case of moduli of stable commutative surfaces, we show that

Arithmetic aspects of moduli of sheaves on curves

We describe recent work on the arithmetic properties of moduli spaces of stable vector bundles and stable parabolic bundles on a curve over a global field. In particular, we describe a connection

Intersection Sheaves for Abel maps

Intersection sheaves, i.e., the Deligne pairings, were first introduced by Deligne in the setting of Poincaré duality for étale cohomology, and later in his work on the determinant of cohomology.

Complete moduli spaces of branchvarieties

Abstract The space of subvarieties of ℙ n with a fixed Hilbert polynomial is not complete. Grothendieck defined a completion by relaxing “variety” to “scheme”, giving the complete Hilbert scheme of

Sheaves on Artin stacks

Abstract We develop a theory of quasi-coherent and constructible sheaves on algebraic stacks correcting a mistake in the recent book of Laumon and Moret-Bailly. We study basic cohomological

On Coverings of Deligne–Mumford Stacks and Surjectivity of the Brauer Map

The paper proves a result on the existence of finite flat scheme covers of Deligne–Mumford stacks. This result is used to prove that a large class of smooth Deligne–Mumford stacks with affine moduli

Quot Functors for Deligne-Mumford Stacks

Abstract Given a separated and locally finitely-presented Deligne-Mumford stack 𝒳 over an algebraic space S, and a locally finitely-presented 𝒪𝒳-module ℱ, we prove that the Quot functor

Hom-stacks and restriction of scalars

Fix an algebraic space S, and let X and Y be separated Artin stacks of finite presentation over S with finite diagonals (over S). We define a stack HomS(X ,Y) classifying morphisms between X and Y.
