Let A be an n Γ— n matrix over an arbitrary field F of the form AI, 1 AI, z] A = A2.1 A2,2 J, where A1, 1 ~ F pΓ—p, A2. 2 ~ F qΓ—q, and p + q = n. We characterize the possible nmnber of nontrivial invariant polynomials of A, when the submatrices A L 2 and A2, 1 are prescribed.

This paper gives necessary and sufficient conditions for the existence of a matrix [ A 1 A2], where A 1 is square, with prescribed block similarity class and a prescribed submatrix that does not contain principal entries of A 1.
