A note on the continuity of the joint numerical range

Abstract

本 論文에서는 Banach 代數 B(H)에서 unitary space C?의 convex subset들의 closure의 集合 Σ에로의 함수인 the joint numerical range는 operator topologies에 대해서 항상 連續임을 밝혔다.

The purpose of this note is to discuss the continuity of the joint numerical ranige from a Banach algebra B(H) into a collection Σ of the closure of convex subsets of a unitary space C? in the operator topologies.
