Abstract

We make a geometric study of the Geometric Rank of tensors recently introduced by Kopparty et al. Results include classification of tensors with degenerate geometric rank in C3C3C3C^3\otimes C^3\otimes C^3, classification of tensors with geometric rank two, and showing that upper bounds on geometric rank imply lower bounds on tensor rank.
