关于同余式$x^x\equiv λ\pmod p$

On the congruence $x^x\equiv λ\pmod p$

Javier Cilleruelo, Moubariz Z. Garaev

摘要:

本文得到了关于同余式$$ x^{x}\equiv λ\pmod p;\quad x\in \mathbb{N},\quad x\le p-1, $$解的个数的上界估计问题的几个新结果,其中$p$是大素数,$λ$是与$p$相同的整数.我们的论点是基于Shkredov和Shteinikov最近对子群三角和的估计。

英文摘要:

In the present paper we obtain several new results related to the problem of upper bound estimates for the number of solutions of the congruence $$ x^{x}\equiv λ\pmod p;\quad x\in \mathbb{N},\quad x\le p-1, $$ where $p$ is a large prime number, $λ$ is an integer corpime to $p$. Our arguments are based on recent estimates of trigonometric sums over subgroups due to Shkredov and Shteinikov.
