Abstract
We show that the set of complex skew-symmetric matrix polynomials of even grade , i.e., of degree at most , and (normal) rank at most is the closure of the single set of matrix polynomials with certain, explicitly described, complete eigenstructure. This complete eigenstructure corresponds to the most generic complex skew-symmetric matrix polynomials of even grade and rank at most . The analogous problem for the case of skew-symmetric matrix polynomials of odd grade is solved in [Linear Algebra Appl., 536:1-18, 2018].
