Minimal degree equations for curves and surfaces (variations on a theme of Halphen)

Algebraic Geometry 2019-06-20 v1

Abstract

Many classical results in algebraic geometry arise from investigating some extremal behaviors that appear among projective varieties not lying on any hypersurface of fixed degree. We study two numerical invariants attached to such collections of varieties: their minimal degree and their maximal number of linearly independent smallest degree hypersurfaces passing through them. We show results for curves and surfaces, and pose several questions.
