A characterization of the set of lines either external to or secant to an ovoid in PG(3, q)

چکیده
In this paper we prove that in PG(3, q) a q 4+q2 2 −set of lines, having exactly q8−q7−q4+q3 8 pairs of skew lines, of type (m,m+ q 2+q 2 ) with respect to stars of lines and of type (m′,m′ + q 2+q 2 ) with respect to ruled planes, is the set of lines either external to or secant to an ovoid.

OVOIDS OF PG(3, q), q EVEN, WITH A CONIC SECTION
Throughout this paper we will assume that q is even. We will be considering ovoids of PG(3, q) which contain a conic as a plane section by using different representations of the classical generalized quadrangle of order q. An oal / of PG(2, q) is a set of q1 points of PG(2, q), with no three collinear. Let F be a line of PG(2, q) ; then F is incident with zero, one or two points of / and is a...
متن کاملOvoids and Translation Ovals
An ooid in a 3-dimensional projective geometry PG(3, q) over the field GF(q), where q is a prime power, is a set of q#1 points no three of which are collinear. Because of their connections with other combinatorial structures ovoids are of interest to mathematicians in a variety of fields ; for from an ovoid one can construct an inversive plane [3], a generalised quadrangle [11], and if q is e...
متن کاملGroup–theoretic characterizations of classical ovoids
An ovoid of PG(3, q), q > 2, is a set of q + 1 points of PG(3, q), no three of which are collinear. The only known ovoids of PG(3, q) are the elliptic quadrics, which exist for all q, and the Suzuki-Tits ovoids, which exist for q = 2, e ≥ 3 odd, [10]. It is well known that for odd q, the only ovoids are the elliptic quadrics. For even q, the ovoids have been classified only for q up to and incl...
متن کاملMaximal subgroups of finite orthogonal groups stabilizing spreads of lines
We prove that, for q odd and n ≥ 3, the group G = On(q) · 2 is maximal in either the orthogonal group O2n(q) or the special orthogonal group SO2n(q). The group G corresponds to the stabilizer of a spread of lines of PG(2n − 1, q) in which some lines lie on a quadric, some are secant to the quadric and others are external to the quadric.
متن کاملLine 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...
