L^P空间上的Müntz有理逼近

Rational Approximation of Müntz in L^P Spaces

本文考虑了L^P空间上的M(u|¨)ntz有理系统{x^(λn)},改进了系指数{λ_n}_(n=1)~∞所要满足的条件,得到了逼近的Jackson型定理。

This essay deals with the rational system on L^P spaces,and tries to improve the index{λ_n}_(n=1)~∞.The necessary conditions lead to a conclusion of Jackson Theorem of approximation.
