In this paper we extend concepts of statistical limit superior and inferior (as introduced by Fridy and Orhan) to Iâˆ’limit superior and inferior and give some Iâˆ’analogue of properties of statisticalâ€¦ (More)

The concept of statistical convergence was presented by Steinhaus in 1951. This concept was extended to the double sequences by Mursaleen and Edely in 2003. Karakus has recently introduced theâ€¦ (More)

In this paper, we introduce a modification of the SzÃ¡sz-Mirakjan type operators of two variables which preserve f0 (x, y) = 1 and f3 (x, y) = x 2 + y. We prove that this type of operators enables aâ€¦ (More)

In this paper, using the concept of statistical A-summability which is stronger than the A-statistical convergence, we prove a Korovkin type approximation theorem for sequences of positive linearâ€¦ (More)

In this paper, using the concept of A -statistical convergence for double sequences, we investigate a Korovkin-type approximation theorem for sequences of positive linear operator on the space of allâ€¦ (More)

This paper deals with a modification of the classical SzÃ¡sz-Mirakjan type operators of two variables. It introduces a new sequence of non-polynomial linear operators which hold fixed the polynomialsâ€¦ (More)

In this paper, using the concept of statistical A-summability which is stronger than classical convergence and A-statistical convergence, we obtain a Korovkin-type approximation theorem for doubleâ€¦ (More)

In this paper, using a matrix summability method we obtain a Korovkin type approximation theorem for a sequence of positive linear operators defined on a modular space.
