This dissertation consists of two parts . in part one , the weighted approximation by the linear operators in classical spaces and approximation in orlicz spaces are studied ; in part two , the approximation of multivariate linear operators is discussed 本學位論文分為上下兩篇,上篇主要為一元線性算子在經(jīng)典空間的加權逼近和orlicz空間的逼近:下篇為多元線性算子在經(jīng)典空間的逼近和加權逼近。
The second part has summarized from the one - dimension and multivariate respects the abundant approximation properties of bernstein polynomials , mainly including the estimation of approximation degree , derivative approximation , linear combination approximation and weighted approximation 第二部分從一元和多元兩個方面系統(tǒng)總結了bernstein算子豐富的逼近性質,主要包括逼近度估計、導數(shù)逼近、線性組合逼近和加權逼近等
