论文摘要
给定的组$ a $ a $ a和$ b $,在a*b $中,元素$ g \的第2020个功率的最小换向器长度是多少?对这个问题的详尽答案仍然未知,但是我们几乎可以给出一个答案:最低是两个数字之一(仅取决于$ a $ a $ and $ b $)。还考虑了其他类似的问题。
Given groups $A$ and $B$, what is the minimal commutator length of the 2020th (for instance) power of an element $g\in A*B$ not conjugate to elements of the free factors? The exhaustive answer to this question is still unknown, but we can give an almost answer: this minimum is one of two numbers (simply depending on $A$ and $B$). Other similar problems are also considered.
