Zhang, We Peng et Wang, Xiao Ying, On the Fourth Power Mean of the Character Sums Over Short Intervals, Acta mathematica Sinica. English series (Print) , 23(1), 2006, pp. 153-164
The main purpose of this paper is to study the mean value properties of the character sums over the interval [1,p8) by using the mean value theorems of the Dirichlet L-functions, and give an interesting mean value formula for this study
