Lower and upper bounds for some generalized arcs

Abstract

Let Fq\mathbb{F}_q be a field with qq elements. In this note, we study some generalized arcs, that is, sets of Fq\mathbb{F}_q-points in the projective plane P2(Fq)\mathbb{P}^2(\mathbb{F}_q) such that no six of them are on a conic. First, we consider the geometric configurations of such generalized arcs for small values of qq and then we give some upper and lower bounds for the cardinality of complete generalized arcs, i.e. generalized arcs which are not contained in a bigger one.
