چکیده
|
In this paper, firstly we show that some classical properties for cauchy dual and moore-penrose inverse of composition operators, such as complex symmetric and aluthge transform on $l^{2}(sigma)$. secondly we give a characterization for some operator classes of weak $p$-hyponormal via moore-penrose inverse of composition operators. finally, some examples are then presented to illustrate that, the moore-penrose inverse of composition operators lie between these classes.
