论文摘要
周期性整数持续分数(PICF)是常规周期性持续分数(RPCF)的概括。经典的RPCF扩展非理性数字是唯一的。但是,对于PICF扩展而言,它不再是唯一的。因此,确定所有非理性数字扩展是一个自然的问题。在本文中,我们确定了无正方形整数的平方根的某些类型的PICF膨胀。为了获得此结果,它在Brock-Elkies-Jordan中出现的某些PCF品种的整数点起着重要作用。作为这些结果的应用,我们从无正方形整数的平方根以及RPCF扩展的PICF扩展中获得了Pell方程的基本解决方案。
Periodic integer continued fractions (PICFs) are generalization of the regular periodic continued fractions (RPCFs). It is classical that a RPCF expansion of an irrational number is unique. However, it is no longer unique for a PICF expansion. Hence it is a natural problem to determine all PICF expansions of irrational numbers. In this paper, we determine certain type PICF expansions of square roots of positive square-free integers. To obtain this result, it plays an important role to determine integer points on certain PCF varieties appeared in Brock-Elkies-Jordan. As an application of these results, we obtain fundamental solutions of the Pell equations from PICF expansions of square roots of positive square-free integers as well as the RPCF expansions.
