Approximation for periodic functions via statistical \(A\)-summability (English)
0 references
Using the concept of statistical \(A\)-summability, the authors obtain Korovkin type approximation results for sequences of positive linear operators on the space of \(2\pi \)-periodic, continuous functions on \(\mathbb R\). The test functions are \(1, \cos x, \sin x\). Rates of convergence are also investigated.
