非自由有理点的新序列

群论 2021-01-12 v2 数论

摘要

我们给出 τ\tau 的一些新的无穷有理值族(其中部分为有理数的平方),使得由矩阵 (1101)\left( \begin{smallmatrix} 1 & 1 \\ 0 & 1 \end{smallmatrix} \right)(10τ1)\left( \begin{smallmatrix} 1 & 0 \\ \tau & 1 \end{smallmatrix} \right) 生成的群甚至半群不是自由的。

Fixed a typo: I had written "free" instead of "non-free" in a few places; and made a few other minor edits
