Divergence properties of the generalised Thompson groups and the braided-Thompson groups

Golan and Sapir \cite{MR3978542} proved that the Thompson’s groups $F$, $T$ and $V$ have linear divergence. In the current paper, we focus on the divergence properties of several generalisation of the Thompson’s groups, we first consider the Brown-Thompson’s groups $F_n$, $T_n$ and $V_n$ and found out that these groups also have linear divergence function. We then consider the braided Thompson’s groups $BF$ and $\widehat{BF}$ and $\widehat{BV}$ together with the result in \cite{Kodama:2020to} we conclude that theses groups have linear divergence.
