On the fourth power mean of the analogous general Kloosterman sum

TextWith the aids of elementary methods, the fourth power mean value of the analogous general Kloosterman sums C(m,n,k,χ;q)C(m,n,k,χ;q) is studied, and an explicit formula is obtained. It shows that C(m,n,k,χ;q)C(m,n,k,χ;q) enjoys good mean value distribution properties.VideoFor a video summary of this paper, please visit https://youtu.be/FZmy08BTpH8.
