The Binet-Cauchy Theorem for the Hyperdeterminant of boundary format multidimensional Matrices

Carla Dionisi, Giorgio Ottaviani

Let $A$ , $B$ be multidimensional matrices of boundary format respectively $\prod_{i = 0}^{p} (k_{i} + 1)$ , $\prod_{j = 0}^{q} (l_{j} + 1)$ . Assume that $k_{p} = l_{0}$ so that the convolution $A * B$ is…
