Structural Stability of Matrix Pencils and Matrix Pairs Under Contragredient Equivalence

A complex matrix pencil A− ⋋ B is called structurally stable if there exists its neighborhood in which all pencils are strictly equivalent to this pencil. We describe all complex matrix pencils that are structurally stable. It is shown that there are no pairs ( M,N ) of m × n and n × m complex matri...
