由扩域定义的高度的Schanuel定理

Schanuel's theorem for heights defined via extension fields

Christopher Frei, Martin Widmer

摘要:

令$k$为数域,令$θ$为非零代数数,令$H(\cdot)$为代数数上的Weil高度。在回答T。Loher和D. W. Masser,我们证明了用$H(αθ)\leq X$计算$α\in k$个数的一个渐近公式.我们还证明了一类新的高度函数定义通过$k$的扩域的渐近计数结果。这为洛赫和马瑟的问题及其概括提供了概念框架。此外,我们分析了Loher和Masser问题的渐近公式中的主导常数。特别地,我们证明了一个尖锐的上界的经典Schanuel常数。

英文摘要:

Let $k$ be a number field, let $θ$ be a nonzero algebraic number, and let $H(\cdot)$ be the Weil height on the algebraic numbers. In response to a question by T. Loher and D. W. Masser, we prove an asymptotic formula for the number of $α\in k$ with $H(αθ)\leq X$. We also prove an asymptotic counting result for a new class of height functions defined via extension fields of $k$. This provides a conceptual framework for Loher and Masser's problem and generalizations thereof. Moreover, we analyze the leading constant in our asymptotic formula for Loher and Masser's problem. In particular, we prove a sharp upper bound in terms of the classical Schanuel constant.
