Multiplication Operator with BMO Symbols and Berezin Transform
We discuss multiplication operator with a special symbol on the weighted Bergman space of the unit ball. We give the necessary and sufficient conditions for the compactness of multiplication operator on the weighted Bergman space of the unit ball.

Multiplication operators on the space of functions of bounded variation
In this paper,we study the properties of the multiplication operator acting on the bounded variation space BV[0, 1]. In particular,we show the existence of non-null compact multiplication operators on BV[0, 1] and non-invertible Fredholm multiplication ...

Spectrum of One-Dimensional Potential Perturbed by a Small Convolution Operator: General Structure
We consider an operator of multiplication by a complex-valued potential in L2(R), to which we add a convolution operator multiplied by a small parameter. The convolution kernel is supposed to be an element of L1(R), while the potential is a Fourier image

The spectrum generated by s-numbers and pre-quasi normed Orlicz-Cesáro mean sequence spaces
In this article, we study some topological properties of the multiplication operator on Orlicz-Cesáro mean sequence spaces equipped with the pre-quasi norm and the pre-quasi operator ideal constructed by this sequence space and s-numbers.

Eigenvalues of s-type operators on C ( p ) $C(p)$ equipped with a pre-quasi norm
We investigate some new topological properties of the multiplication operator on C ( p ) $C(p)$ defined by Lim (Tamkang J. Math. 8(2):213–220, 1977) equipped with the pre-quasi-norm and the pre-quasi-operator ideal formed by this sequence space and s ...
