模函数的乘法无关性

Multiplicative independence of modular functions

Guy Fowler

摘要:

我们提供了一个新的,小学的乘法独立性的成对不同的$\mathrm{GL}_2^+(\mathbb{Q})$ -模块化的$j$ -功能,结果最初由于皮拉和Tsimerman的翻译证明。因此,我们能够将这一结果推广到更广泛的一类模函数。我们表明,这个类包括一组由模函数自然产生的Borcherds电梯的某些弱全纯模形式。对于$f$模函数属于这个类,我们推导出,对于每个$n \geq 1$,有限的$n$ -元组的不同$f$ -特殊点是乘法依赖和最小的这个属性。这推广了Pila和Tsimerman关于奇异模的一个定理。然后,我们将展示这些结果与Zilber-粉红猜想的混合志村品种$Y(1)^n \times \mathbb{G}_{\mathrm{m}}^n$的子品种,并证明了一些特殊情况下,这个猜想。

英文摘要:

We provide a new, elementary proof of the multiplicative independence of pairwise distinct $\mathrm{GL}_2^+(\mathbb{Q})$-translates of the modular $j$-function, a result due originally to Pila and Tsimerman. We are thereby able to generalise this result to a wider class of modular functions. We show that this class includes a set comprising modular functions which arise naturally as Borcherds lifts of certain weakly holomorphic modular forms. For $f$ a modular function belonging to this class, we deduce, for each $n \geq 1$, the finiteness of $n$-tuples of distinct $f$-special points that are multiplicatively dependent and minimal for this property. This generalises a theorem of Pila and Tsimerman on singular moduli. We then show how these results relate to the Zilber--Pink conjecture for subvarieties of the mixed Shimura variety $Y(1)^n \times \mathbb{G}_{\mathrm{m}}^n$ and prove some special cases of this conjecture.
