A computing strategy and programs to resolve the Gerstenhaber Problem for commuting triples of matrices

preprint2020arXivOpen access

Abstract

We describe a MATLAB program that could produce a negative answer to the Gerstenhaber Problem by the construction of three commuting n×nn \times n matrices A,B,CA,B,C over a field FF such that the subalgebra F[A,B,C]F[A,B,C] they generate has dimension greater than nn. This problem has remained open for nearly 60 years, following Gerstenhaber's surprising result (Annals Math.) that dim⁡F[A,B]≤n\dim F[A,B] \le n for any two commuting matrices A,BA,B. The property fails for four or more commuting matrices. We also make the MATLAB files freely available.
