Theorems of Second Korovkin Type with respect to Triangular $A$-Statistical Convergence
Theorems of Second Korovkin Type with respect to Triangular $A$-Statistical Convergence
This article is a continuation of our previous works. We mainly investigate a Korovkin type theorem for double sequences of positive linear operators defined in the space of all $2\pi $-periodic and real valued continuous functions on the real two-dimensional space with help of the concept of triangular $A$-statistical convergence, which is a kind of statistical convergence for double real sequences. Also, we analyze the rate of convergence of double operators in this via modulus of continuity.
