The $G$-stable rank for tensors and the cap set problem

Vol. 16 (2022), No. 5, 1071–1097

Abstract

We introduce the $G$ -stable rank of a higher order tensors over perfect fields. The $G$ -stable rank is related to the Hilbert–Mumford criterion for stability in geometric invariant theory. We will relate the $G$ -stable rank to the tensor rank and slice rank. For numerical applications, we express the $G$ -stable rank as a solution to an optimization problem. Over the field $𝔽_{3}$ we discuss an application to the cap set problem.
