Sojfer, G. A. Free subsemigroups of the affine group, and the Schoenflies-Bieberbach theorem. (English) Zbl 0759.22014 Lie groups, their discrete subgroups, and invariant theory, Adv. Sov. Math. 8, 197-204 (1992). [For the entire collection see Zbl 0742.00088.]Some properties of the subsemigroups of the affine group acting discontinuously on an affine space are pointed out. A generalization of the Schoenflies-Bieberbach theorem is also proved.
