Deferred Nörlund statistical relative uniform convergence and Korovkin-type approximation theorem

In this paper, we define the concept of statistical relative uniform convergence deferred Nörlund mean and prove a general Korovkin-type approximation theorem by using method. As an application, use classical Bernstein polynomials for defining operator that satisfies our new but does not satisfy given before. Additionally, estimate rate approximating positive linear operators means modulus continuity.
