Sets of matrices with given joint numerical range

Naum Krupnik, Ilya M. Spitkovsky

Research output: Contribution to journalArticlepeer-review


The following question is addressed: To what extent the n-tuple of m × m Hermitian matrices is determined by its joint numerical range? The cases m = 2, n arbitrary and m = n = 3 are considered in detail.
