Approximation properties of modified q- Phillips operators

Abstract

引进一类修正Q-PHIllIPS算子,并研究该算子列的一些逼近性质.得到算子列的一个kOrOVkIn型收敛定理,给出了算子列收敛速度的估计和一个VOrOnOVSkAJA型结果.In this paper,a kind of modified q- Phillips operators is introduced,some approximate properties of the operators are studied.A convergence theorem of Korovkin type is established.Also,an estimate for the rate of convergence and a Voronovskaja- type result are given.国家自然科学基金资助项目(61170324); 福建省自然科学基金资助项目(2014J01021); 福建省教育厅科技资助项目(2012JA12324
