The structure of maximal zero-sum free Sequences
Gautami Bhowmik, Immanuel Halupczok, Jan-Christoph Schlage-Puchta
Let n be an integer, and consider finite sequences of elements of the group Z/nZ x Z/nZ. Such a sequence is called zero-sum free, if no subsequence has sum zero. It is known that t…

Trees of definable sets over the p-adics
Immanuel Halupczok
To a definable subset of Z_p^n (or to a scheme of finite type over Z_p) one can associate a tree in a natural way. It is known that the corresponding Poincare series P(X) = \sum_i…

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.
