Quadratic unitary Cayley graphs of finite commutative rings

Xiaogang Liu, Sanming Zhou

The purpose of this paper is to study spectral properties of a family of Cayley graphs on finite commutative rings. Let $R$ be such a ring and $R^{\times}$ its set of units. Let $Q_R…

On the Lower Bound of the Divisibility of Exponential Sums in Binomial Case

Xiaogang Liu

Francis Castro, et al [2] computed the exact divisibility of families of exponential sums associated to binomials $F (X) = a X^{d_{1}} + b X^{d_{2}}$ over $F_{p}$ , and a conjecture…
