In this paper, we introduce the notions of Sϕ-polynomial and S-minimal value set polynomial where ϕ is a polynomial over a finite field 𝔽q and S is a finite subset of an algebraic closure of 𝔽q. We study some properties of these polynomials and we prove that the polynomials used by Garcia, Stichtenoth and Thomas in their work on good recursive tame towers are Sϕ-minimal value set polynomials for ϕ=xm, whose S-value sets can be explicitly computed in terms of the monomial xm.

最小值集多项式与有限域上的函数域的分支塔之间的联系

在本文中,我们介绍了小号φ-多项式和小号- 最小值集多项式其中φ是有限域上的多项式𝔽q小号是一个代数闭包的有限子集𝔽q. 我们研究了这些多项式的一些性质,我们证明了 Garcia、Stichtenoth 和 Thomas 在他们关于良好递归驯服塔的工作中使用的多项式是小号φ- 最小值集多项式φ=X,谁的小号-值集可以根据单项式显式计算X.
