Exact Divisibility of Exponential Sums Associated to Binomials over finite fields

Francis Castro, Raúl Figueroa, Puhua Guan

In this paper we compute the exact divisibility of exponential sums associated to binomials $F(X)=a{X}^{d_1}+b{X}^{d_2}$. In particular, for the case where $\max\{d_1,d_2\}\leq\sqrt{…
