Linear spaces and preservers of persymmetric triangular matrices of bounded rank-two / Ng Zhen Chuan

Let F be a field and n an integer > 2. We say that a square matrix A is persymmetric if A is symmetric in the second diagonal. Let STn(F) denote the linear space of all n x n persymmetric upper triangular matrices over F. A subspace S of STn(F) is said to be a space of bounded rank-two matrices i...
