特征2中的一些平面单项式

Some planar monomials in characteristic 2

Zachary Scherr, Michael E. Zieve

摘要:

有限域上的平面函数产生有限射影平面和其他组合对象。它们最初只定义在奇数特征,但最近周介绍了一个定义在偶数特征,产生类似的应用。本文证明了$\mathbb{F}_{2^r}$上的某些函数是平面的,从而证明了Schmidt和Zhou的一个猜想.证明的关键是关于次数- $(q-1)$ Fermat曲线$x^{q-1}+y^{q-1}=z^{q-1}$上的$\mathbb{F}_{q^3}$ -有理点的一个新结果.

英文摘要:

Planar functions over finite fields give rise to finite projective planes and other combinatorial objects. They were originally defined only in odd characteristic, but recently Zhou introduced a definition in even characteristic which yields similar applications. In this paper we show that certain functions over $\mathbb{F}_{2^r}$ are planar, which proves a conjecture of Schmidt and Zhou. The key to our proof is a new result about the $\mathbb{F}_{q^3}$-rational points on the degree-$(q-1)$ Fermat curve $x^{q-1}+y^{q-1}=z^{q-1}$.
