On the approximation by convolution type double singular integral operators

In this paper, we prove the pointwise convergence and the rate of pointwise convergence for a family of singular integral operators in two-dimensional setting in the following form: \begin{equation*} L_{λ}\left( f;x,y\right) =\underset{D}{\iint }f\left( t,s\right) K_{λ}\left( t-x,s-y\right) dsdt,\text{ }\left( x,y\right) \in D, \end{equation*} where $D=\left \langle a,b\right \rangle \times \left \langle c,d\right \rangle $ is an arbitrary closed, semi-closed or open rectangle in $\mathbb{R}^{2}$ and $% λ\in Λ,$ $Λ$ is a set of non-negative indices with accumulation point $λ_{0}$. Also, we provide an example to support these theoretical results. In contrast to previous works, the kernel function $K_{λ}\left( t,s\right) $ does not have to be even, positive or 2$π-$periodic.

On statistical approximation properties of $q$-Baskakov-Szasz-Stancu operators

In the present paper, we consider Stancu type generalization of Baskakov-Szász operators based on the q-integers and obtain statistical and weighted statistical approximation properties of these operators. Rates of statistical convergence by means of the modulus of continuity and the Lipschitz type maximal function are also established for operators.
