Cyclic and elementary abelian caps in projective spaces Original Research Article

This article presents cyclic and elementary abelian caps in projective spaces. Different classes of groups all yielding an infinite class of caps are presented. The link with pseudo-cyclic codes is discussed, and we show that a result by Boros and Szőnyi in PG(2,q2) can be extended to PG(2n,q2) for proving that the (q2n+1+1)/(q+1)-caps in PG(2n,q2) constructed by Ebert and Kestenband are equivalent.
