On a classical zero-sum invariant II: Disproof of a long-standing conjecture
Alfred Geroldinger, Guoqing Wang, Wenkai Yang
For a nontrivial finite abelian group , let be the smallest integer such that every zero-sum free sequence over of length at least has the following…
On a zero-sum problem arising from factorization theory
Aqsa Bashir, Alfred Geroldinger, Qinghai Zhong
We study a zero-sum problem dealing with minimal zero-sum sequences of maximal length over finite abelian groups. A positive answer to this problem yields a structural description…
Sets of lengths in atomic unit-cancellative finitely presented monoids
Alfred Geroldinger, Emil Daniel Schwab
For an element of a monoid , its set of lengths is the set of all positive integers for which there is a factorization $a=u_1 \cdot \ld…
On the Davenport constant and on the structure of extremal zero-sum free sequences
Alfred Geroldinger, Manfred Liebmann, Andreas Philipp
Let with $1 < n_1 \t ... \t n_r$ be a finite abelian group, , and let denote the maxi…
