Minimal cellular resolutions of powers of graphs

Commutative Algebra 2026-03-04 v2

Abstract

Let GG be a connected graph and let I(G)I(G) denote its edge ideal. We classify when I(G)nI(G)^n, for n1n \ge 1, admits a minimal Lyubeznik resolution. We also give a characterization for when I(G)nI(G)^n is bridge-friendly, which, in turn, implies that I(G)nI(G)^n has a minimal Barile-Macchia cellular resolution.
