    • Abstract


      Let 𝑝 be an odd prime and 𝑎 be an integer coprime with 𝑝. Denote by $N(a,p)$ the number of pairs of integers $b, c$ with $bc\equiv a(\mathrm{mod} p),1\leq b, c < p$ and with $b, c$ having different parity. The main purpose of this paper is to study the mean square value problem of $N(a,p)-\frac{1}{2}(p-1)$ over interval $(N, N+M]$ with $M,N$ positive integers by using the analytic methods, and finally by obtaining a sharp asymptotic formula.
