ABSaV.ACT. Let ~¢' = (~, £.a, ~, =) be a Moufang-Klingenberg plane coordinatized by a local alternative ring R. We define the projectivities of a line 9 in J¢ geometrically as products of perspectivities. It is shown that under certain conditions the group of projectivities of 9 is generated by the

## CROSS-RATIOS IN MOUFANG-KLINGENBERG PLANES ABSVRACT. Certain geometric groups operating on a line g in a Moufang-Klingenberg plane J/ are described algebraically in terms of the underlying alternative ring R. For the case of the dual numbers R = A + Ae (A alternative field, e2= 0) a notion of c

This paper deals with neighbor-preserving epimorphisms between arbitrary projective Klingenberg planes. Our main result is an algebraic characterization of such epimorphisms which generalizes a theorem of J. C. Ferrar and F, D. Veldkamp [2] for neighbor-preserving epimorphisms between projective rin

This paper deals with epimorphisms between arbitrary projective Klingenberg planes which preserve the non-neighbor relation. Our main result is an algebraic characterization of such epimorphisms which generalizes a theorem of F. D. Veldkamp for distant preserving epimorphisms between projective rin
