Abstract

Let Σb\Sigma_b be a closed Riemann surface of genus bb. We give an account of some results obtained in the recent papers \cite{CaPol19, Pol20, PolSab21} and concerning what we call here \emph{pure braid quotients},namely non-abelian finite groups appearing as quotients of the pure braid group on two strands P2(Σb)\mathsf{P}_2(\Sigma_b). We also explain how these groups can be used in order to provide new constructions of double Kodaira fibrations.
