WebWe will prove that if a finite abelian group is a direct product of its subsets such that one subset has four elements and the others have prime cardinalities, then at least one of the factors must be periodic. WebBy the famous theorems of Redei, a set of q points in AG(2, q) (respectively p points in AG(2, p), p prime) is either a line or it determines at least √ q+1 (respectively p+3 2 ) directions.

WebTheorem 1 shows that the expansion of T by A consists in the addition to T of the excess part of A, revision in the addition of A to the excess part of T and contraction in the removal of the overlapping part of A from T. As a technical comment, note that Theorem 1 also takes into account cases of ‘‘vacuous’’ change (Hansson 1999, p. 66). WebAbstract. By Rédei’s theorem, if a finite abelian group is factored into normalized subsets of prime cardinality, then at least one of the factors is a subgroup of the group. The special case when G is of type ( p, p) plays an important part of the proof of the general case and has interesting geometric and combinatorial applications.
