بررسی ویژگی هایی از عملگر های امید شرطی وزن دار

In this paper, we estimate the essential norm of weighted conditional expectation operators on Bergman spaces by means of related Carleson measures. As a consequence, we get an equivalence condition for compactness of these operators And we will mention an example. Our results extend similar results that were proven for multiplication operators on Bergman spaces.
