Generic skew-symmetric matrix polynomials with fixed rank and fixed odd grade

Rings and Algebras 2017-03-20 v1

Abstract

We show that the set of m×mm \times m complex skew-symmetric matrix polynomials of odd grade dd, i.e., of degree at most dd, and (normal) rank at most 2r2r is the closure of the single set of matrix polynomials with the certain, explicitly described, complete eigenstructure. This complete eigenstructure corresponds to the most generic m×mm \times m complex skew-symmetric matrix polynomials of odd grade dd and rank at most 2r2r. In particular, this result includes the case of skew-symmetric matrix pencils (d=1d=1).
