But recent results relating semi?elds and coding theory (and also the study of generalized Galois rings) have stimulated the study of these rings from a strictly algebraic point of view. In this work we follow the second path, the term semi?eld is used to describe an algebraic system which satis?es all properties of a ?eld except for commutativity and associativity of multiplication. Semi?elds are of special interest today because the projective planes constructed from them have rather remarkable properties.
