Canonical forms of $2\times 3\times 3$ tensors over the real field, algebraically closed fields, and finite fields

Michel Lavrauw, John Sheekey

We classify the orbits of elements of the tensor product spaces ${\mathbb{F}}^2\otimes {\mathbb{F}}^3\otimes {\mathbb{F}}^3$ for all finite; real; and algebraically closed fields…
