Existence of unimodular element in a projective module over symbolic Rees algebras
Published 13 Jan 2023 in math.AC | (2301.05394v1)
Abstract: Let $A$ be a symbolic (or an extended symbolic) Rees algebra (need not be Noetherian) of dimension $d$. Let $P$ be a finitely generated projective $A$-module of rank $\geq$ $d$. Then P has a unimodular element. This improves the classical result of Serre for the mentioned class of algebras.
