Marzieh Mehrazin, Maryam Amyari, Mohsen Erfanian Omidvar

摘要:

本文定义了数值域$W_{o}(\cdot)$的新概念,并证明了它的基本结果。定义了数值半径$ω_{o}(\cdot)$,并证明了$$ω_{o}(T)\leq||| T|||\leq 2ω_{o}(T).$$

英文摘要:

In this paper, we define a new concept of numerical range $W_{o}(\cdot)$ and prove its basic results. We also define the numerical radius $ω_{o}(\cdot)$ and prove that $$ω_{o}(T)\leq||| T|||\leq 2ω_{o}(T).$$
