| Abstract: | Recently some classical operator quasi-interpolants were introduced to obtain much faster convergence.We consider left Gamma quasi-interpolants and give a pointwise simultaneous approximation equivalence theorem with ω2r(4)λ(f,f)∞ by means of unified the classical modulus and Ditzian-Totick modulus. |
