Finite semifields

2011
About this title: Galois geometry is the theory that deals with substructures living in projective spaces over finite fields, also called Galois fields. This collected work presents current research topics in Galois geometry, and their applications. Presented topics include classical objects, blocking sets and caps in projective spaces, substructures ...

Generalized semifields

A triple (S, +, · ) is said to be semiring iff S is a set and + and · are binary operations on S such that (1) (S,+) is a commutative semigroup, (2) (S, ·) is commutative semigroup, (3) (x+y) ·z=x·z+y·z for all x, y, z, ɛ , S. A semiring (D,+, ·) is said to be a ratio semiring iff (D, ·) is a group.
