正特征局部域域上Catalan型数的插值

Interpolation of numbers of Catalan type in a local field of positive characteristic

Greg W. Anderson

摘要:

设$k$为正特征的局部域。设$L$是$k$的余紧离散子群.设$U$是$k$的开紧子群.设$\ell$、$u$和$a$是$k$的元素,其中$a$非零。我们研究了产物$\prod_{0\neq x\in (\ell+L)\cap a(u+U)}x$随$a$变化的行为。我们的主要结果融合了调和分析和局部类域论,局部地证实了作者最近提出的关于整体函数域的一个猜想(math.NT/0407535)。

英文摘要:

Let $k$ be a local field of positive characteristic. Let $L$ be a cocompact discrete subgroup of $k$. Let $U$ be an open compact subgroup of $k$. Let $\ell$, $u$ and $a$ be elements of $k$, with $a$ nonzero. We study the behavior of the product $\prod_{0\neq x\in (\ell+L)\cap a(u+U)}x$ as $a$ varies. Our main result, which blends harmonic analysis and local class field theory, provides local confirmation of a conjecture concerning global function fields recently made by the author (math.NT/0407535).
