The Banach Numerical Range for Finite Linear Operators
(Modern Scientific Press, Florida, USA, 2019-01)
The numerical range has been studied extensively in Hilbert spaces. Properties of the numerical range such as non-emptiness, containment of the spectrum and in particular, convexity have been proved and results have ...
