چکیده
If φ is a nontrivial automorphism of a thick building ∆ of purely infinite type, we prove that there is no bound on the distance that φ moves a chamber. This has the following group-theoretic consequence: If G is a group of automorphisms of ∆ with bounded quotient, then the center of G is trivial.

We show that dimensional doubly dual hyperovals over F2 define bent functions. We also discuss some known and a few new examples of dimensional doubly dual hyperovals and study the associated bent functions.

Connections are made between deficiency one α-flokki and Baer groups of associated α-flokki translation planes, extending the theory of Johnson and Payne-Thas. The full collineation group of an α-flokki is completely determined. Many of the ideas are extended to the infinite case.

The set of points obtained by projecting a quadric from a point off the quadric on a hyperplane has many interesting properties. Hirschfeld and Thas [12, 13] provided a characterization of this set, only by means of its intersection pattern with lines. However, their result only holds when the finite field has even order. Here, we extend their result to finite fields of odd order.

In 1965 Knuth [4] showed that from a given finite semifield one can construct further semifields manipulating the corresponding cubical array, and obtain in total six semifields from the given one. In the case of a rank two commutative semifield (the semifields corresponding to a semifield flock) these semifields have been investigated in [1], providing a geometric connection between these six ...

Let be Cayley’s ruled cubic surface in a projective three-space over any commutative field . We determine all collineations fixing , as a set, and all cubic forms defining . For both problems the cases turn out to be exceptional. On the other hand, if then the set of simple points of can be endowed with a non-symmetric distance function. We describe the corresponding circles, and we establish t...
