An Improvement on Olson's Constant for Z_p+Z_p

Gautami Bhowmik, Jan-Christoph Schlage-Puchta

For a prime number p greater than 6000, the Olson's constant for the group Z_p+Z_p is given by Ol(Z_p+Z_p)=p-1+Ol(Z_p).

Zero-sum free sequences with small sum-set

Gautami Bhowmik, Immanuel Halupczok, Jan-Christoph Schlage-Puchta

Let A be a zero-sum free subset of Z_n with |A|=k. We compute for k\le 7 the least possible size of the set of all subset-sums of A.

Gautami Bhowmik, Jan-Christoph Schlage-Puchta

We determine Davenport's constant for all groups of the form .
