Norm inequalities involving a special class of functions for sector matrices
Abstract In this paper, we present some unitarily invariant norm inequalities for sector matrices involving a special class of functions. In particular, if Z = ( Z 11 Z 12 Z 21 Z 22 ) is a 2 n × 2 n $2n\times 2n$ matrix such that numerical range of Z is contained in a sector region S α $S_{\alpha }...
