Title: On the parity conjecture for Hilbert schemes of points on threefolds
Abstract: The Hilbert scheme of points in affine n-dimensional space, which parametrizes zero-dimensional subschemes with a fixed degree, is a fundamental parameter space in algebraic geometry. Quot schemes are a generalization of Hilbert schemes, parametrizing finite length quotients of a locally free sheaf. We will explore some interesting phenomena and problems about these spaces that are specific to the three-dimensional case, focusing on the tangent space and recent progress on the parity conjecture of Okounkov and Pandharipande. This is joint work with Alessio Sammartano.
