WebIn projective geometry an oval is a point set in a plane that is defined by incidence properties. The standard examples are the nondegenerate conics. However, a conic is … WebIn any nite projective plane of order q, an oval is a set of q+ 1 points, no three of which are collinear. In the classical plane PG(2;q) over GF(q), a nondegenerate conic is the prototypical oval. If the order of a plane is even, then the tangents to an oval all pass through a point that is called the nucleus of the oval.
An oval in a finite projective plane of order q is a (q + 1, 2)-arc, in other words, a set of q + 1 points, no three collinear. Ovals in the Desarguesian (pappian) projective plane PG(2, q) for q odd are just the nonsingular conics. However, ovals in PG(2, q) for q even have not yet been classified. In an arbitrary finite projective plane of odd order q, no sets with more points than q + 1, no three of which are collinear, exist, as first pointed out by Bose in a 1947 paper on applications of this s…
