生成迹非零平方变元的三值Kloosterman和幂矩的无穷族递归公式:$O(2n+1,2^{r})$情形

Infinite Families of Recursive Formulas Generating Power Moments of Ternary Kloosterman Sums with Trace Nonzero Square Arguments: $O(2n+1,2^{r})$ Case

Dae San Kim

摘要:

本文构造了$O(2n+1,q)$中关于特殊正交群$SO(2n+1,q)$的某个极大抛物子群的四个具有双陪集的三元线性码的无限族.这里$q$是三的幂。然后得到了两个无穷族递归公式,一个产生具有$``$迹非零平方参数的Kloosterman和的幂矩,另一个产生它们的偶次幂矩.这两个族都用与$O(2n+1,q)$中的那些双陪集相关联的码和与辛群$Sp(2n,q)$中的类似双陪集相关联的码中的权重的频率来表示。这是通过Pless幂矩恒等式和利用与正交群$O(2n+1,q)$的$"$高斯和的求值相关的双陪集上的指数和的显式来完成的。

英文摘要:

In this paper, we construct four infinite families of ternary linear codes associated with double cosets in $O(2n+1,q)$ with respect to certain maximal parabolic subgroup of the special orthogonal group $SO(2n+1,q)$. Here $q$ is a power of three. Then we obtain two infinite families of recursive formulas, the one generating the power moments of Kloosterman sums with $``$trace nonzero square arguments" and the other generating the even power moments of those. Both of these families are expressed in terms of the frequencies of weights in the codes associated with those double cosets in $O(2n+1,q)$ and in the codes associated with similar double cosets in the symplectic group $Sp(2n,q)$. This is done via Pless power moment identity and by utilizing the explicit expressions of exponential sums over those double cosets related to the evaluations of $"$Gauss sums" for the orthogonal group $O(2n+1,q)$.
