Scarf complexes of graphs and their powers

Sara Faridi, TÃ i Huy HÃ, Takayuki Hibi +1

Every multigraded free resolution of a monomial ideal I contains the Scarf multidegrees of I. We say I has a Scarf resolution if the Scarf multidegrees are sufficient to describe a…

Minimal cellular resolutions of powers of graphs

Trung Chau, TÃ i Huy HÃ, Aryaman Maithani

Let $G$ be a connected graph and let $I (G)$ denote its edge ideal. We classify when $I (G)^{n}$ , for $n \geq 1$ , admits a minimal Lyubeznik resolution. We also give a characterization…
