Finite semifields and nonsingular tensors
In this article, we give an overview of the classification results in the theory of finite semifields (note that this is not intended as a survey of finite semifields including a complete state of the art (see also Remark 1.10)) and elaborate on the approach using nonsingular tensors based on Liebler (Geom Dedicata 11(4):455-464, 1981)
Sublines of prime order contained in the set of internal points of a conic
In \cite{BALLBLOKHUISLAVRAUW200*} it was shown that if
then there are no subplanes of order contained
in the set of internal points of a conic in \PG(2,q^n), odd,
. In this article we improve this bound in the case where is prime to
, and prove a stronger theorem by considering
sublines instead of subplanes. We also explain how one can apply this result
to flocks of a quadratic cone in \PG(3,q^n), ovoids of , rank two commutative
semifields, and eggs in \PG(4n-1,q)
