Recently the following theorem in combinatorial group theory has been proved: Let G be a finite abelian group and let A be a sequence of members of G such that |A| |G| +D(G)&1, where D(G) is the Davenport constant of G. Then A contains a subsequence B such that |B|= |G| and b # B b=0. We shall prese

Let < be a "nite additive subgroup of a "eld K of characteristic p'0. We consider sums of the form S F (< : )" TZ4 (v# )F for h50 and 3 K. In particular, we give necessary and su$cient conditions for the vanishing of S F (<; ), in terms of the digit sum in the base-p expansion of h, in the case that
