The numerical range and decomposable numerical range of matrices
Linear and Multilinear Algebra, 1991Let m and n be positive integers such that 1≤m≤n. Denote by the set of all n×m complex matrices. For a matrix , the mth decomposable numerical range of A is the set When m=1, it reduces to the classical numerical range of A which is denoted by W(A). It is known that is contaned in W(Cm (A)), where Cm (A) is the mth compound of A. In this paper we study
