It is well known that, when a full rank observable pair (C,A) is slightly perturbed, the new observability indices k′ are majorized by the initial ones k, k≻k′. Conversely, any indices k′ majorized by k can be obtained by perturbing (C,A). Th

Topological properties of a matrix equation of Sylvester type are considered. This equation is related to the block similarity between rectangular matrices, and the passage matrices in this equivalence relation are solutions. A local criterion for th

We are concerned with the following problem: Let Xi, i1,2, be vector spaces over C ;Yi subspaces of Xi, i1,2; and fi:Yi→Xi, i1,2, linear m defined on a subspace. We characterize the invariants of block similarity of f1⊗f2:Y1⊗Y2→ X1
