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…
About the stability of the tangent bundle restricted to a curve
Chiara Camere
Let C be a smooth projective curve with genus g>1 and Clifford index c(C) and let L be a line bundle on C generated by its global sections. The morphism i:C -->P(H^0(L))=P is well-…
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.
Implicitization of Bihomogeneous Parametrizations of Algebraic Surfaces via Linear Syzygies
Laurent Busé, Marc Dohm
We show that the implicit equation of a surface in 3-dimensional projective space parametrized by bi-homogeneous polynomials of bi-degree (d,d), for a given positive integer d, can…
Alexander polynomials: Essential variables and multiplicities
Alexandru Dimca, Stefan Papadima, Alexander I. Suciu
We explore the codimension one strata in the degree-one cohomology jumping loci of a finitely generated group, through the prism of the multivariable Alexander polynomial. As an ap…
