Resolucions lineals i ideals de grafs

Abstract

[en] In this work, we study some of the correspondences between commutative algebra and graph theory. We start with an introduction on edge and cover ideals that lead into introducing the algebra basic tools that lets us state Fröberg’s Theorem on linear resolutions of edge ideals and chordal graphs. The work ends with a proof of Fröberg’s Theorem given by Adam Van Tuyl, based on monomial splittings and some properties of chordal graphs.
