# N(p) number of solution to x^x =1 (mod p) Miklós Schweitzer 2010

Let $p$ a prime number and $N(p)$ the number of solution to $x^x \equiv 1$ (mod $p$) in $1\leq x \leq p$ . Prove that for sufficiently large $p$ there exist a constant $c < \frac{1}{2}$ such that $N(p) \leq p^c$

@Mahan:i am sure that your either of your question is going to get closed,as you posted the same at MO here its from my past experience, i suggest you just to post either at MO or at Math stack exchange,and wait for 2 days for your answer,i am sure that question gets closed ,i suggest that you close it before someone suggests you,as i had many bitter experiences posting in that way,thank you ,decision is left to you ,anyway –  Iyengar Sep 10 '11 at 11:41
and if you feel your Question to be a good one ,i mean if it is a Research level Question ,its better you post it at MO, –  Iyengar Sep 10 '11 at 11:43
buts its just a request,dont take it as a command,i neither have rights to say so,nor i am not a owner of MO,so i said just for your benefit,as some people just look at such small mistakes,and comment without answering the main question,which happened in my case many times –  Iyengar Sep 10 '11 at 11:48
@Mahan: Yes. On the left of each answer, you see an up-arrow, followed by a number, followed by a down-arrow. For your own questions, below the down-arrow you will also see a tick-mark. Clicking that will accept the answer, while clicking the arrows will allow you to upvote or downvote answers. The number inbetween shows the (number of upvotes) - (number of downvotes) for that answer. –  TMM Sep 10 '11 at 16:59
