An Axiomatic Approach to Tensor Rank Functions

Functional Analysis 2020-12-10 v1 Rings and Algebras

Abstract

Recent work of Qi et al. arXiv:2004.11240v7 proposes a set of axioms for tensor rank functions. The current paper presents examples showing that their axioms allow rank functions to have some undesirable properties, and a stronger set of axioms is suggested that eliminates these properties. Two questions raised by Qi et al. involving the submax rank function are also answered.
