Newton-Okounkov body, Rees algebra, and analytic spread of graded families of monomial ideals

Abstract

Let $\mathcal{I}=\{I_k{\}}_{k\in \mathbb{N}}$ be a graded family of monomial ideal. We use the Newton-Okounkov body of $\mathcal{I}$ to: (a) give a characterization for the Noetherian property of the Rees algebra of the family; and (b) present a combinatorial interpretation for the analytic spread of the family. We also apply these results to investigate the generation type and the Veronese degree of the symbolic Rees algebra of a monomial ideal.
