BookDOI
General Galois geometries
TL;DR: In this paper, the authors define Hermitian varieties, Grassmann varieties, Veronese and Segre varieties, and embedded geometries for finite projective spaces of three dimensions.
Journal ArticleDOI
Generalized quadrangles and flocks of cones
TL;DR: It is proved that with a set of q upper triangular 2 × 2-matrices over GF(q) of a certain type, there corresponds a generalized quadrangle of order (q2, q) and with each flock of the quadratic cone there corresponds such a setof matrices.
Journal ArticleDOI
Ovoids and spreads of finite classical polar spaces
TL;DR: In this article, it was shown that the polar space Q(2n, q) arising from a non-singular elliptic quadric has no ovoid, and the polar spaces H(n,q), q even, and H(q, q even) have no ovo.
Book ChapterDOI
Projective Geometry over a Finite Field
TL;DR: In this article, the authors focus on projective geometry over a finite field and define a k-arc in projective plane, PG (n, q) is a set K of k points with k ≥ n + 1 such that no n+ 1 points of K lie in a hyperplane.
