Elementary Divisors of Tensor Products The elementary divisors of a tensor product of linear transformations have been known for 40 years. This paper provides a short, easily accessible proof of these results, and points out an interesting combinatorial consequence of the proof. CACM January, 1975 Marcus, M.
