Ido Efrat

For a prime number $p$ and a free profinite group $S$ , let $S^{(n, p)}$ be the $n$ th term of its lower $p$ -central filtration, and $S^{[n, p]}$ the corresponding quotient. Using tool…

Michael Chapman, Ido Efrat

We make a systematic study of filtrations of a free group F defined as products of powers of the lower central series of F. Under some assumptions on the exponents, we characterize…
