L_p范数下随机连续函数空间中的Weierstrass定理
Weierstrass’s theorem in L_p spaces of random continuous function
【摘要】 通过概率方法对随机连续函数的多项式逼近性质进行了研究.借助随机Bernstein算子给出了Lp范数下随机系数多项式逼近的定性估计,进而推广了Weierstrass定理.
【Abstract】 The purpose of this article is to investigate polynomial approximation properties of random continuous function by the probability method.We obtained the qualitative estimation by random Bernstein’s operator with Lpnorm and extended Weierstrass’ s theorem to random continuous function spaces further.
