## dedicated to k. doerk on his 60th birthday Given two subgroups U V of a finite group which are subnormal subgroups of their join U V and a formation , in general it is not true that U V = U V . A formation is said to have the Wielandt property if this equality holds universally. A formation wit

The classical solution of the Riemann᎐Hilbert problem attaches to a given representation of the fundamental group a regular singular linear differential equation. We present a method to compute this differential equation in the case of a representation with finite image. The approach uses Galois cov
We consider a class of Hopf algebras having as an invariant a generalized Cartan matrix. For a Hopf algebra of this kind, we prove that it is finite dimensional if and only if its generalized Cartan matrix is actually a finite Cartan matrix (under some mild hypothesis). These results allow us to cla
We compute the quantum double, braiding, and other canonical Hopf algebra constructions for the bicrossproduct Hopf algebra H associated to the factorization of a finite group X into two subgroups. The representations of the quantum double are described by a notion of bicrossed bimodules, generalisi
