✦ Synopsis
Let D be a division ring with centre k. We show that D contains the k-group algebra of the free group on two generators when D is the ring of fractions of a suitable skew polynomial ring, or it is generated by a polycyclic-by-finite group which is not abelian-by-finite, or it is the ring of fractions of the universal enveloping algebra of a finite-dimensional Lie algebra of characteristic zero.
