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 Lp norm and extended Weierstrass's theorem to random continuous function spaces further.

Key words: random continuous function, Weierstrass's theorem, random Bernstein's operator, random coefficient polynomial
