Abstract:

‎The main purpose of this note is to define an analogues of the numerical radius related to the matricial range‎. ‎However‎, ‎we will find relations between the numerical radius and matricial range of an operator‎. ‎The tone of the paper is mostly expository‎.

Keywords:

Numerical range‎ , ‎matricial range‎ , ‎completely positive mapping‎ , numerical radius‎
