Abstract: | Let m be a positive integer. Fix a nontrivial additive character for each finite field Fq. To state the first result of this paper, we also fix r distinct multiplicative characters 1,..., r for each finite field Fq with more than r elements. We shall prove that when varies over multiplicative characters of Fq other than the m-th roots of the r-tuples
of angles of Gauss sums are asymptotically equidistributed on the r-dimensional torus (S1)r as q goes to infinity.The n-dimensional Kloosterman sum over Fq at a Fq× is
One can define the angle (q,a) of Kln(q,a) in a suitable way. We shall prove that when a varies over nonzero elements of Fq, the q–1 angles (q,am) of Kloosterman sums are asymptotically equidistributed as q goes to infinity.Mathematics Subject Classification (2000) 11L05, 14F20 |
