Abstract


In this manuscript, we construct a complex (p, q) Lorentz-Schurer operator for q > p > 1 and discuss the approximation properties on a compact disk. Based on the Voronovskaja’s type theorem and exact orders, we also obtain quantitative estimate by the (p, q) Lorentz-Schurer operator attached to analytic functions in the compact disk.
