文摘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 ωφλ^2r(f,t)∞ by means of unified the classical modulus and Ditzian-Totick modulus.
