Approximation by a power series summability method of Kantorovich type Szász operators including Sheffer polynomials

Abstract

Abstract The main purpose of this paper is to use a power series summability method to study some approximation properties of Kantorovich type Szász–Mirakyan operators including Sheffer polynomials. We also establish Voronovskaya type result.
