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
Alessio Cela, Aitor Iribar Lopez
In this paper we compute the integral Chow ring of the moduli stack of Prym pairs of genus 2 with integral coefficients.
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 , th…

Alessio Cela, Alberto Landi
This paper is the second in a series devoted to describing the integral Chow ring of the moduli stacks of hyperelliptic Prym pairs. For fixed genus , the stack…
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…
Chow ring of the stack of plane nodal curves
Alessio Cela, Ajith Urundolil Kumaran, Xiaohan Yan
We compute the rational Chow ring of the moduli stack of planar nodal curves of fixed degree and express it in terms of tautological classes. Along the way, we extend Vial's result…
