Fastgeordnete affine lokale Ternärringe und pregeordnete Biternärringe. (Quasiordered affine local ternary rings and preordered biternary rings.). (German) Zbl 0711.51001

In Czech. Math. J. 30(105), 556-568 (1980; Zbl 0467.51016), the author has codified the notion of preordered affine local ternary rings (fastgeordnete affine lokale Ternärringe) as an algebraic counterpart of the concept of arbitrary preordered affine Klingenberg planes.
For the special case of affine Hjelmslev planes, in J. Geom. 23, 14-44 (1984; Zbl 0545.51006)], C. A. Baker, N. D. Lane, J. W. Lorimer, and J. A. A. Laxton have introduced another notion of preorderings, geometrically equivalent to the author’s, but related to a quite different algebraic setting in terms of preordered Hjelmslev biternary rings. (This paper seems not to be correctly quoted by the author; [3] 4.1 should read [3] 5.1 and [3] Lemma 7, Beh. 6 should be [3] 5.4.)
The author gives an algebraic proof that, in case the underlying plane is Hjelmslev, both algebraic concepts are equivalent.
