Some results on the joint higher numerical ranges and radii of matrices
Gholamreza Aghamollaei; Mohammad Ali Nourollahi;Abstract
In this paper, some algebraic properties of the joint k-numerical radius, joint k-spectral radius and the joint k-norm of matrices are investigated. Moreover, using the joint higher numerical ranges of diagonal matrices which are convex polyhedrons, a description for the shape of the higher numerical ranges of matrix polynomials is given.
