Mohsen Kian, Mahdi Dehghani, Mostafa Sattari

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
