Abstract:
Amultidimensional nonnegative matrix is called polystochastic if the sum of the entries in each line is equal to 1. The set of all polystochastic matrices of order n and dimension d forms a convex polytope Ωd n. In the present paper, we compare known bounds on the number of vertices of the polytope Ωd n and prove that the number of vertices of Ωd 3 is doubly exponential in d.
