Commuting maps on rank k triangular matrices
Let n >= 2 be an integer and let F be a field with vertical bar F vertical bar >= 3. Let T-n(F) be the ring of n x n upper triangular matrices over F with centre Z. Fixing an integer 2 <= k <= n,we prove thatan additive map psi: T-n (F) -> T-n(F) satisfies A psi (A) = psi(A)A for all...
