The Generalized Numerical Range with Completely Symmetric Function

    Research output: Contribution to journalArticlepeer-review

    Abstract

    A necessary and sufficient condition for the m-numerical range H k m (A) of a matrix A with the completely symmetric function C k to be a line segment in the complex plane is given in this note.
