A generalization of Phillips operators by using the Appell polynomials of class A ( 2 ) $A^{(2)}$

Abstract The current paper discusses some important approximation properties of a new modification of the Phillips operators with the help of A ( 2 ) $A^{(2)}$ class Appell polynomials. Firstly, we present the convergence rate of our new operators by using modulus of continuity. Then we establish a...
