Zero-sumfree sequences in cyclic groups and some arithmetical application Alfred Geroldinger, Yahya Ould Hamidoune (2002) Journal de théorie des nombres de Bordeaux We show that in a cyclic group with n elements every zero-sumfree sequence S with length | S | ≥ n + 1 2 contains some element of order n with high multiplicity.
