A stronger version of Neumann's BFC-theorem

A celebrated theorem of B. H. Neumann states that if $G$ is a group in which all conjugacy classes are finite with bounded size, then the derived group $G'$  is finite.  In this talk we will discuss a stronger version of  Neumann's result and some consequences for finite and profinite groups.  Based on a joint work with Pavel Shumyatsky.
