On the Chow rings of classifying spaces for classical groups
Luis Alberto Molina Rojas, Angelo Vistoli
We show how the stratification method, introduced by Vezzosi in his study of PGL_3, provides a unified approach to the known computations of the Chow rings of the classifying space…
On the cohomology and the Chow ring of the classifying space of PGL_p
Angelo Vistoli
We investigate the integral cohomology ring and the Chow ring of the classifying space of the complex projective linear group PGL_p, when p is an odd prime. In particular, we deter…
Stacks of cyclic covers of projective spaces
Alessandro Arsie, Angelo Vistoli
We define stacks of uniform cyclic covers of Brauer-Severi schemes, proving that they can be realized as quotient stacks of open subsets of representations, and compute the Picard…
Algebraic orbifold quantum products
Dan Abramovich, Tom Graber, Angelo Vistoli
The purpose of this note is to give an overview of our work on defining algebraic counterparts for W. Chen and Y. Ruan's Gromov-Witten Theory of orbifolds. This work will be descri…
Higher algebraic K-theory for actions of diagonalizable groups
Gabriele Vezzosi, Angelo Vistoli
We study the K-theory of actions of diagonalizable group schemes on noetherian regular separated algebraic spaces: our main result shows how to reconstruct the K-theory ring of suc…
Twisted bundles and admissible covers
Dan Abramovich, Alessio Corti, Angelo Vistoli
The cherry on top of this stacky paper is the following: for any g>1 we give a finite group G such that the moduli space of connected admissible G-covers of genus g is a smooth, fi…
