关于正规折纸数的无理指数

On the irrationality exponent of the regular paperfolding numbers

Yingjun Guo, Wen Wu, Zhixiong Wen

摘要:

本文改进了Allouche \emph{et al.} \cite{APWW98}的方法,计算了正则折纸序列的Hankel行列式,证明了Hankel行列式序列模2是周期为10的周期序列,从而回答了Coon猜想\cite{CV12} .然后推广Bugeaud的方法\cite{Bugeaud11},得到了某些一般超越数的无理性指数的精确值.利用上述结果,我们证明了正则折纸数的无理性指数恰为2。

英文摘要:

In this paper, improving the method of Allouche \emph{et al.} \cite{APWW98}, we calculate the Hankel determinant of the regular paperfolding sequence, and prove that the Hankel determinant sequence module 2 is periodic with period 10 which answers Coon's conjecture \cite{CV12}. Then we extend Bugeaud's method \cite{Bugeaud11} to obatin the exact value of the irrationality exponent for some general transcendental numbers. Using the results above, we prove that the irrationality exponents of the regular paperfolding numbers are exactly 2.
