双调和ABEL-POISSON算子对共轭HLDER函数类的逼近(续)
On Approximation of the Functions of Conjugate Hlder Classes By Biharmonic Abel-Poisson Operator
【摘要】 文[8]建立了双调和Abel-Poisson算子对共轭Hlder函数类的逼近上界和逼近下界.在此构造一个新的函数,提高了文[8]中的下界,改进上界与下界的差距.
【Abstract】 In paper [8],We studied the approximation of the functions of conjugate Hlder class by biharmonic poisson integral,and gave the upper and lower bound.This paper will construct a new function,which improves the lower bound of paper [8] and reduces the difference of the upper and lower bound.
