圆对称函数的对数系数
The Logarithmic Coefficients of Circularly Symmetric Functions

运用构造一个非负函数和对复变函数模的积分进行估计的方法,对圆对称函数的对数系数| bn|进行了研究,得到估计| bn|≤An-1log(n+1),n=1,2,…,这里A是一个绝对常数,指数-1是准确的.
A non-negative function and estimate the integration of model of a complex function have been constructed.The logarithmic coefficients |bn| of circularly symmetric functions is discussed by this method.The estimate |bn|≤Anlog(n+1)(n=1,2,3,…)is given,where A is an absolute constants,and the exponent -1 is sharp
