Title: Rational singularities and $q$-birational morphism
(Submitted on 11 Jan 2023 (this version), latest version 27 Mar 2024 (v4))
Abstract: In this paper, we generalize the notion of rational singularities for any reflexive sheaf of rank $1$ and prove generalizations of standard facts about rational singularities. Moreover, we introduce the notion of $(B_{q+1})$ as a dual notion of well-known Serre's notion of $(S_{q+1})$ and prove a theorem about $q$-birational morphism.
