Abstract

In the present paper, we study the rate of convergence of Szasz type and Kantorovich-Szasz type operators involving Sheffer polynomials with the help of modulus of continuity and examine these type operators including reverse Bessel polynomials which are Sheffer type. Furthermore, we compute error estimation for a function f by operators containing reverse Bessel polynomials.
