Ruikai Chen, Sihem Mesnager

AI总结:

本文研究有限域三次和四次扩域上的平面三项式,利用二次型联系与经典代数工具取得成果,并提出可推导更多扩域平面函数的通用方法。

摘要:

Dembowski和Ostrom引入的平面函数是从有限域到其自身的函数,能生成有限射影平面。然而,它们仅存在于奇特征的有限域中。由于理论价值及在诸多领域的深刻广泛应用,过去十年间它们备受关注。本文聚焦于有限域三次和四次扩域上的平面三项式。我们的成果是利用其与二次型的联系及有限域上的经典代数工具获得的。此外,鉴于方法的通用性,所提出的方法论可用于在部分有限扩域上推导出更多平面函数。

英文摘要:

Planar functions, introduced by Dembowski and Ostrom, are functions from a finite field to itself that give rise to finite projective planes. They exist, however, only for finite fields of odd characteristics. They have attracted much attention in the last decade thanks to their interest in theory and those deep and various applications in many fields. This paper focuses on planar trinomials over cubic and quartic extensions of finite fields. Our achievements are obtained using connections with quadratic forms and classical algebraic tools over finite fields. Furthermore, given the generality of our approach, the methodology presented could be employed to drive more planar functions on some finite extension fields.
