Geometry of Smooth Extremal Surfaces
Anna Brosowsky, Janet Page, Tim Ryan +1
We study the geometry of the smooth projective surfaces that are defined by Frobenius forms, a class of homogenous polynomials in prime characteristic recently shown to have minima…
Minimal free resolutions of sheaves on the projective plane and the stable base locus decomposition of their moduli spaces
Manuel Leal, César Lozano Huerta, Tim Ryan
The purpose of this paper is to incorporate minimal free resolutions into the study of the birational geometry of the moduli space of coherent sheaves on the plane with character $…
Irreducibility and singularities of some nested Hilbert schemes
Tim Ryan, Gregory Taylor
Let be a smooth projective surface over . We study the local and global geometry of the nested Hilbert scheme of points . In particular, we show th…
The geometry of Hilbert schemes of two points on projective space
Tim Ryan
In this paper, we give three bases for the cohomology groups of the Hilbert scheme of two points on projective space. Then, we use these bases to compute all effective and nef cone…
