Baskakov算子线性组合加权同时逼近的正定理
Positive Result of Weighted Simultaneous Approximation by the Linear Combinations of Baskakov Operators
摘要
Abstract
Under the Jacobi weight function ω(t),by using equivalence relation between the smooth modulus ωτφλ (f,)ω and the K-functional,the approximation properties of the linear combination of Baskakov operators to the functions in space C[0,∞) are studied,and its positive result of weighted simultaneous approximation are given,to further expand the results of previous.关键词
