چکیده

We determine all point-sets of minimum size in PG(2, q), q odd that meet every external line to a conic in PG(2, q). The proof uses a result on the linear system of polynomials vanishing at every internal point to the conic and a corollary to the classification theorem of all subgroups of PGL(2, q).

Line partitions of internal points to a conic in PG(2, q)

All sets of lines providing a partition of the set of internal points to a conic C in PG(2, q), q odd, are determined. There exist only three such linesets up to projectivities, namely the set of all nontangent lines to C through an external point to C, the set of all nontangent lines to C through a point in C, and, for square q, the set of all nontangent lines to C belonging to a Baer subplane...

A spectrum result on minimal blocking sets with respect to the planes of PG(3, q), q odd

This article presents a spectrum result on minimal blocking sets with respect to the planes of PG(3, q) , q odd. We prove that for every integer k in an interval of, roughly, size [q 2 /4, 3q 2 /4] , there exists such a minimal blocking set of size k in PG(3, q) , q odd. A similar result on the spectrum of minimal blocking sets with respect to the planes of PG(3, q) , q even, was presented in [...

On sets without tangents and exterior sets of a conic

A set without tangents in PG(2, q) is a set of points S such that no line meets S in exactly one point. An exterior set of a conic C is a set of points E such that all secant lines of E are external lines of C. In this paper, we first recall some known examples of sets without tangents and describe them in terms of determined directions of an affine pointset. We show that the smallest sets with...

Dimensions of some binary codes arising from a conic in PG(2, q)

Let O be a conic in the classical projective plane PG(2, q), where q is an odd prime power. With respect to O, the lines of PG(2, q) are classified as passant, tangent, and secant lines, and the points of PG(2, q) are classified as internal, absolute and external points. The incidence matrices between the secant/passant lines and the external/internal points were used in [5] to produce several ...

Sets with a Large Numbers of Nuclei on a Conic

For large q we characterize the (q + 1)-sets in PG(2, q), q odd, having more than 0.326q nuclei on a conic. In the process more information about the structure of (q + 1)-sets having a large number of nuclei on a conic is obtained.
