Linear & Multilinear Algebra | 2010

A remark on numerical range of semi-hyponormal operators

Muneo Chō; Tadasi Huruya

Let U be the unilateral shift on ℓ2. For any complex numbers α and β, put T = αU + βU* and S = T 2. Then we show that the operator S is convexoid.

Integral Equations and Operator Theory | 2005
