摘要
研究了Bα空间中Bernstein Durrmeyer多项式的加权逼近,得到了强型正定理和弱型逆定理,从而导出了逼近的特征定理.
A weighted approximation of Bernstein-Durrmeyer polynomials in B_α spaces is studied, and the direct theorem of strong type and converse theorem of weak type are obtained. Thereby the characteristic theorem of approximation is induced.
