Generalization of numerical range of polynomial operator matrices

Suppose that  is a polynomial matrix operator where  for , are  complex matrix and let  be a complex variable. For an  Hermitian matrix , we define the -numerical range of polynomial matrix of  as , where . In this paper we study   and our emphasis is on the geometrical properties of . We consider...
