# On the generalization of Golomb's conjecture

Let $p$ be a sufficiently large prime number, $r$ be any given positive integer. Suppose that $a_1,\,\dots,\,a_r$ are pairwise distinct and not zero modulo $p$... Let $N(a_1,\,\dots,\,a_r;\,p)$ denote the number of $\alpha_1,\,\dots,\,\alpha_r,\,\beta$, which are primitive roots modulo $p$, such that $\alpha_1+\beta\equiv a_1,\,\dots,\,\alpha_r+\beta\equiv a_r\,({\rm mod}\,p).$ In the first version of this paper, we proved an asymptotic formula for $N(a_1,\,\dots,\,a_r;\,p)$ so that we could answer an open problem of Wenpeng Zhang and Tingting Wang. But we found that our result had been included in a paper of L. Carlitz in 1956, which is explained in the additional remark below. read more
