On the C-numerical range of a matrix
Copyright policy )On the C-numerical range of a matrix
The author gives a condition for the \(C\)-numerical range \(W(C,T)\) of \(T\) being a line segment. He also obtains the result that if the \(C\)- numerical range \(W(C,T)\) of \(T\) is nowhere dense in \(\mathbb{R}^ 2\) then the matrices \(C\) and \(T\) are normal matrices.
