On Cross-Ratio in some Moufang-Klingenberg Planes
Authors/Creators
Description
In this paper we are interested in Moufang-Klingenberg
planesM(A) defined over a local alternative ring A of dual numbers.
We show that a collineation of M(A) preserve cross-ratio. Also, we
obtain some results about harmonic points.
