Some combinatorial results on the classification of lines in Desarguesian Hjelmslev planes. (English) Zbl 0940.51012
Summary: In this paper, we investigate some combinatorial results on the classification of lines in the Hjelmslev plane arising from a given regular conic of this plane. The main result is Theorem 2.3 concerning the number of tangents, secants, imaginary tangents, nonsecants and zero tangents.
