## Given a matrix quadruple e 3 we completely characterize the feedback invariants of the matrix pair e 1 e 2 ! Y e 3 e 4 ! Y for all possible selections of matrices P F n 1 Γn 2 and P F n 2 Γn 2 .

The problem of the possible similarity classes of all the matrices obtained by small perturbations on some rows of a given complex square matrix is under consideration. Some necessary conditions on these similarity classes are provided. The near converse problem is also studied: under what condition
The challenge consists in describing the relationships between the Kronecker invariants of a matrix pencil and one of its subpencils. For a given subpencil, an algorithm for constructing a matrix pencil with prescribed Kronecker invariants should also be proposed.
