Numerical Radius Isometries

Linear and Multilinear Algebra, 2002
Let V be a direct sum of full matrix algebras, or the algebra of block upper triangular matrices. Suppose r ( A ) is the numerical radius of $A \in V$ . We characterize mappings $f: V \rightarrow V$ that satisfy $r(\;f(A)-f(B)) = r(A-B) \ {\rm for \ all} \ A, B \in V$ .
