Abstract
Abstract
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.
