Abstract

Given a positive integer n, a finite field Fq of q elements (q odd), and a non-degenerate quadratic form Q on Fqn, in this paper we study the largest possible cardinality of subsets ε⊆ Fqn with pairwise integral Q-dis- tances; that is, for any two vectors × = (xi,⋯,xn),y = (yi,.,yn) ∞εA,one has Q(x - y) = u2 for some u ∞ F q.
