Bounds on exponential sum in function fields
LI Jiao;CAO Yameng;LI Guoquan;College of Mathematical Science,Tianjin Normal University;
For the polynomial ring Fq[t] over the finite field of Fqwhose characteristic is p,an estimate for the r power of integral of a kind of exponential sum on Fq[t] is obtained. The result is applied to estimate the number of solutions of a kind of homogeneous equations on Fq[t]. And some results of related literatures are extended.
