Abstract:For $A\subseteq {\mathbf{Z}}_m$ and $n\in {\mathbf{Z}}_m$, let $\sigma_A(n)$ be the number of solutions of equation $n=x+y, x,y\in A$. Given a positive integer $m$, let $R_m$ be the least positive integer $r$ such that there exists a set $A\subseteq {\mathbf{Z}}_m$ with $A+A={\mathbf{Z}}_m$ and $\sigma_A(n)\leq r$. Recently, Chen Yonggao proved that all $R_m\leq 288$. In this paper, we obtain new upper bounds of some special type $R_{kp^2}$.
Keywords:Erd\H{o}s-Tur\'{a}n conjecture  additive bases  Ruzsa numbers
