2-friezes的算术

Arithmetics of 2-friezes

Sophie Morier-Genoud

摘要:

我们考虑称为2-frieze的Coxeter-Conway中楣图案的变体。证明了当数组宽度大于4时,存在无穷多个闭整数2-friezes(即只包含正整数)。我们介绍了积分2-friezes上的操作生成更大或更小的封闭积分2-friezes。

英文摘要:

We consider the variant of Coxeter-Conway frieze patterns called 2-frieze. We prove that there exist infinitely many closed integral 2-friezes (i.e. containing only positive integers) provided the width of the array is bigger than 4. We introduce operations on the integral 2-friezes generating bigger or smaller closed integral 2-friezes.
