摘要
引入了修正型Lupas Baskakov积分算子 ,它是由Lupas算子和Baskakov算子复合而得到的。通过分析和研究修正型Lupas Baskakov算子的性质 ,给出了该类算子的Vonorovskya渐近表达式 ,确定了此类算子的饱和阶及平凡类 ,最后建立了修正型Lupas Baskakov积分算子的饱和定理。
A modifi ed Lupas Baskakov integral operator, which compounds Lupas operator and Baskako v operator, is introduced in this paper. By analyzing and researching the proper ties of the modified Lupas Baskakov integral operators, the paper obtains the V onorovskya asymptotic formula, establishes the saturated order and trifle set of the modified Lupas Baskakov integral operators, and then sets up the saturation theorem for this kind of operators.
