Stable maps to quotient stacks with a properly stable point
Andrea Di Lorenzo, Giovanni Inchiostro
We compactify moduli stacks of maps from curves to a large class of quotient stacks admitting projective good moduli spaces. Our construction extends quasimap-theoretic com…
Wall-crossing integral Chow rings of
Luca Battistella, Andrea Di Lorenzo
We compute the integral Chow rings of for . For , these stacks can be obtained by a sequence of weighted blow-ups and blow-downs from…
The Brauer groups of moduli of genus three curves, abelian threefolds and plane curves
Andrea Di Lorenzo, Roberto Pirisi
We compute the -primary torsion of the Brauer group of the moduli stack of smooth curves of genus three over any field of characteristic different from two and the Brauer gro…
A criterion for smooth weighted blow-downs
Veronica Arena, Andrea Di Lorenzo, Giovanni Inchiostro +3
We establish a criterion for determining when a smooth Deligne-Mumford stack is a weighted blow-up. More precisely, given a smooth Deligne-Mumford stack and a Cartier…
Integral Picard group of moduli of polarized K3 surfaces
Andrea Di Lorenzo, Roberto Fringuelli, Angelo Vistoli
We compute the integral Picard group of the moduli stack of polarized K3 surfaces of fixed degree whose singularities are at most rational double points. We also compute the integr…
Effective morphisms and quotient stacks
Andrea Di Lorenzo, Giovanni Inchiostro
We give a valuative criterion for when a smooth algebraic stack with a separated good moduli space is the quotient of a separated Deligne-Mumford stack by a torus. For doing so, we…
