Charakterisierung von Kettengeometrien über semilokalen Algebren.
Dualitäten mit zwei Geraden aus absoluten Punkten in projektiven Ebenen.
Büschelsätze zur Charakterisierung projektiv darstellbarer Zykelebenen.
Über den Rand der projektiven Darstellung von Kettengeometrien auf Grassmann-Mannigfaltigkeiten.
Una caratterizzazione delle fibfrazioni di Galois
In this paper we give a characterisation of the Galois spreads, which are defined in [5] for the construction of the indicator set.
Strutture di André con gruppi di traslazioni transitivi non normali
We give some examples of André-structures admitting translation groups which are transitive on the set of points but which are not normal in the dilatation group. André structures with this property seem to be new in the literature.
