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 $r(\;f(A)-f(B)) = r(A-B) \ {\rm for \ all} \ A, B \in V$ .

Roberts numerical radius orthogonality

Linear and Multilinear Algebra, 2021
We deal with the Roberts numerical radius orthogonality. In the case of 2 × 2 complex matrices, we give some necessary and sufficient conditions for the numerical range to be symmetric by employing...

Polarization Constant for the Numerical Radius

Mediterranean Journal of Mathematics, 2020
Given a symmetric \(m\)-linear mapping \(A:X\times\dots\times X \to Y\) (\(X,Y\) are Banach spaces) and its associated \(m\)-homogeneous polynomial \(\widehat A: X\to Y\), the following polarization inequalities hold: \[\|\hat{A}\| \le \|A\| \le \frac{m^m}{m!} \|\hat{A}\|.\] For specific Banach spaces, the second inequality holds with constants \(C ...
