Monodromy of plane curve singularities and quiver mutation
Roger Casals
The main result of this article shows that the quiver mutation class of a malleable real Morsification uniquely determines the integral monodromy module of a plane curve singularit…
Jordan type of full Perazzo algebras
Pedro Macias Marques, Rosa M. Miró-Roig, Josep Pérez
In this paper, we compute all possible Jordan types of linear forms in any full Perazzo algebra . In some cases we are also able to compute the corresponding Jordan degre…
Characterization of linear spaces of matrices of constant rank from syzygy bundles
Simone Marchesi, Rosa Maria Miró-Roig
In this work, we characterize matrices of linear forms and constant rank, demonstrating that, under some natural assumptions, they are always associated with a syzygy bundle that f…
Smoothings of lci proper schemes
Barbara Fantechi, Rosa M. Miró-Roig
We give criteria for the existence of geometric smoothings of a proper lci scheme or a DM stack as well as for a polarized lci scheme , without assuming that is redu…
Schur powers of the cokernel of a graded morphism
Jan O. Kleppe, Rosa M. Miró-Roig
Let be a graded morphism between free -modules of rank and , respectively, and let be the ideal generated by the minor…
Quasi-homogeneous singularities of projective hypersurfaces and Jacobian syzygies
Aline V. Andrade, Valentina Beorchia, Alexandru Dimca +1
We prove an unexpected general relation between the Jacobian syzygies of a projective hypersurface with only isolated singularities and the nature of its si…
