On the best convergence order of a new class of triangular summation operators
收藏 引用
Journal of Shanghai University(English Edition) 2006年 第5期10卷 399-401页
作者: 孟佳娜 赵连霞 School of Computer Science and Technology Yantai University Yantai 264005 P.R. China Department of Mechanics College of Sciences Shanghai University Shanghai 200444 P.R. China
In this paper, a new class of triangular summation operators based on the equidistant nodes was constructed. It is proved that this class of operators converges uniformly to arbitrary continuous fimctions with the per... 详细信息

Northeastern Mathematical Journal 2001年 第1期17卷 39-44页
作者: 袁学刚 王德辉 DepartmentofMathematicsandInformationalScience YantaiUniversityYantaiShandongProvince264005 DepartmentofMathematics JinlinUniversityChangchun130012
In this paper, an interpolation polynomial operator F n(f; l,x) is constructed based on the zeros of a kind of Jacobi polynomials as the interpolation nodes. For any continuous function f(x)∈C b [-1,1] ... 详细信息
