Numerical ranges and complex symmetric operators in semi-inner-product spaces
Abstract We introduce the numerical range of a bounded linear operator on a semi-inner-product space. We compute the numerical ranges of some operators on ℓ 2 p ( C ) $\ell _{2}^{p}(\mathbb{C})$ ( 1 ≤ p < ∞ ) $(1\le p < \infty )$ and show that the numerical range of the backward shift on an in...
