Coexistence of Elations and Large Baer Groups in Translation Planes
In [6], the compatibility of Baer involutions and elations was studied. Further compatibility results for translation planes of dimension 2 were obtained in [10]. For example [6, Theorem (2.2)], we have the following. Let n be a derivable translation plane of even order q, q # 2, with derivable net N. Let EL denote an elation group in the translation complement which fixes the component L of N ...
متن کاملTranslation Planes and Derivation Sets
Using ideas from algebraic coding theory, a general notion of a derivation set for a pro-jective plane is introduced. Certain geometric codes are used to locate such sets. These codes also lead to upper bounds for the pranks of incidence matrices of translation planes in terms of the dimensions of the associated codes.
متن کاملDual Codes of Translation Planes
We improve on the known upper bound for the minimum weight of the dual codes of translation planes of certain orders by providing a general construction of words of small weight. We use this construction to suggest a possible formula for the minimum weight of the dual p-ary code of the desarguesian plane of order pm for any prime p and any m ≥ 1.

متن کاملA family of translation planes
An infinite family of non-Desarguesian translation planes of order q with kernel GF(q) is constructed, for any odd prime power q. The collineation group of each plane has orbits of lengths 1, q, and q − q on the translation line. The method used for the construction is net replacement, starting from a Dickson-Knuth semifield plane. The planes are constructed via spreads and the spreads via spre...
