Commutator width of Thompson groups
Let $G$ be $F,T$ or $V$ or a topological full group. Let $\rho_1(g)$ be the commutator width of $g$ and $\rho_2(g)$ the minimum number of involutions in a factorization of $g$.Problem 3.1.
- Prove that $\rho_1$ and $\rho_2$ are bounded
- Prove that $\rho_1 = 1$ and $\rho_2 = 3$
- Is there a finitely presented simple group with commutator width greater or equal to $2$?
