Abstract

In this paper, we study typical ranks of 3-tensors and show that there are plural typical ranks for m × n × p tensors over R in the following cases: (1) 3 ≤ m ≤ ρ(n) and (m-1)(n-1)+1 ≤ p ≤ (m-1)n, where ρ is the Hurwitz–Radon function, (2) m=3, n ≡ 3 (mod 4) and p = 2n - 1, (3) m = 4, n ≡ 2 (mod 4), n ≥ 6 and p = 3n - 2, (4) m = 6, n ≥ 4 (mod 8), n ≡ 12 and p = 5n - 4. (5) m = 10, n ≥ 24 (mod 32) and p = 9n - 8.
