The cohomological crepant resolution conjecture for P(1,3,4,4)
Samuel Boissiere, Etienne Mann, Fabio Perroni
We prove the cohomological crepant resolution conjecture of Ruan for the weighted projective space P(1,3,4,4). To compute the quantum corrected cohomology ring we combine the resul…
Quivers, Geometric Invariant Theory, and Moduli of Linear Dynamical Systems
Markus Bader
We use geometric invariant theory and the language of quivers to study compactifications of moduli spaces of linear dynamical systems. A general approach to this problem is present…
A model for the orbifold Chow ring of weighted projective spaces
Samuel Boissiere, Etienne Mann, Fabio Perroni
We construct an isomorphism of graded Frobenius algebras between the orbifold Chow ring of weighted projective spaces and graded algebras of groups of roots of the unity.
A note on toric Deligne-Mumford stacks
Fabio Perroni
We give a new description of the data needed to specify a morphism from a scheme to a toric Deligne-Mumford stack. The description is given in terms of a collection of line bundles…
