K-theory of Weighted Blowups

Veronica Arena, Alessio Cela, Alberto Landi +1

We compute the K-theory of weighted blowups of smooth stacks satisfying the resolution property along smooth centers. As an application, we determine the K-theory of the stack of s…

The Integral Chow Ring of the Stack of Pointed Hyperelliptic Curves

Alberto Landi

We study the integral Chow ring of the stack $H_{g, n}$ parametrizing $n$ -pointed smooth hyperelliptic curves of genus $g$ . We compute the integral Chow ring of $\mathcal{…

The Integral Chow Rings of the Moduli Stacks of Hyperelliptic Prym Pairs III

Alessio Cela, Alberto Landi

This paper is the third and final part of a series devoted to the description of the integral Chow rings of the moduli stacks of hyperelliptic Prym pairs. For a fixed genus $g$ , th…

The Integral Chow Rings of the Moduli Stacks of Hyperelliptic Prym Pairs I

Alessio Cela, Alberto Landi

This paper is the first in a series dedicated to computing the integral Chow rings of the moduli stacks of Prym pairs. In this work, we compute the Chow ring for Prym pairs arising…
