Galois geometry
From Wikipedia, the free encyclopedia
Galois geometry is the branch of finite geometry that is concerned with algebraic and analytic geometry over a finite field (a "Galois" field).[1] More narrowly, a Galois geometry may be defined as a projective space over a finite field.[2]
Objects of study include vector spaces, affine and projective spaces over finite fields and various structures that are contained in them. In particular, arcs, ovals, hyperovals, unitals, blocking sets, ovoids, caps, spreads and all finite analogues of structures found in non-finite geometries.
