我们对待两个不同的方程涉及权力的奇异模。一方面,我们证明了,除了两个可能的(明确指定的)例外,两个不同的奇异模[公式:见正文]使得数[公式:见正文],[公式:见正文]和[公式:见正文]对某些正整数[公式:见正文]线性依赖于[公式:见正文],必须至多是次数[公式:见正文]。这部分地推广了Allombert,Bilu和Pizarro-Madariaga的结果,他们研究了属于[Formula:see text]中定义在[Formula:see text]上的直线的CM点。另一方面,我们表明,与明显的例外,任何两个权力的奇异模的产品不能是一个非零有理数。这推广了Bilu,Luca和Pizarro-Madariaga的结果,他们研究了属于双曲线的CM点[公式:见正文],其中[公式:见正文]。
We treat two different equations involving powers of singular moduli. On the one hand, we show that, with two possible (explicitly specified) exceptions, two distinct singular moduli [Formula: see text] such that the numbers [Formula: see text], [Formula: see text] and [Formula: see text] are linearly dependent over [Formula: see text] for some positive integers [Formula: see text], must be of degree at most [Formula: see text]. This partially generalizes a result of Allombert, Bilu and Pizarro-Madariaga, who studied CM-points belonging to straight lines in [Formula: see text] defined over [Formula: see text]. On the other hand, we show that, with obvious exceptions, the product of any two powers of singular moduli cannot be a non-zero rational number. This generalizes a result of Bilu, Luca and Pizarro-Madariaga, who studied CM-points belonging to a hyperbola [Formula: see text], where [Formula: see text].
