چکیده
|
In [3], we defined the concept of the a-davis-wielandt berezin number for positive operator a. in this paper, we remind this notion and obtain some upper and lower bounds for the a-davis-wielandt berezin number of bounded linear operator on h(ω). as result, we determined the ex-act value of the a-davis--wielandt berezin number of some special type of operator matrices
