Ovals in commutative semifield planes
Archiv Der Mathematik, 1997A translation plane coordinatized by a semifield of odd order admits an orthogonal polarity whose absolute points form an oval \(\Omega\) (necessarily parabolic, having one point on the line at infinity). The collineation group of the plane which stabilizes such an \(\Omega\), acts 2-transitively on the affine points of \(\Omega\). In this paper, it is

Derived semifield planes with affine elations
Journal of Geometry, 1982Derived semifield planes admitting non trivial affine elations with more than one centre are examined in detail and several new examples of such plantes are constructed. A new characterization of the Hall planes of even order among derived semifield planes is also given.

A note on the Boerner-lantz semifield planes
Journal of Geometry, 1992Für die von \textit{V. Boerner-Lantz} [J. Geom. 27, 112-118 (1986; Zbl 0604.12020)] angegebene Konstruktion endlicher distributiver Quasikörper (= semifield) wird die Anzahl der Isomorphietypen so erhaltbarer projektiver Ebenen vorgegebener Ordnung \(p^ 4\) bestimmt: Für \(p\equiv 1\bmod 4\) ist diese Anzahl \(1/4(p-1)\), für \(p\equiv 3\bmod 4\) ist ...
