Let l and k be two integers such that l|k. Define Tlk(X):=X+Xpl++Xpk2l+Xpkl and Slk(X):=XXpl++(1)(k/l1)Xpkl, where p is any prime.

This paper gives explicit representations of all solutions in Fpn to the affine equations Tlk(X)=a and Slk(X)=a, aFpn. The case p=2 was solved very recently in [10]. The results of this paper reveal another solution.

求解有限域上的一些仿射方程

lk为两个整数,使得|ķ。定义ŤķX=X+Xp++Xpķ-2+Xpķ-小号ķX=X-Xp++-1个ķ/-1个Xpķ-,其中p是任何质数。

本文给出了所有解决方案的显式表示 Fpñ 仿射方程 ŤķX=一种小号ķX=一种一种Fpñ。案子p=2最近在[10]中得到解决。本文的结果揭示了另一种解决方案。
