Kemnitz's conjecture
In mathematics, Kemnitz's conjecture states that the centroid of a certain set of lattice points in plane is also a lattice point. It was proved independently in the autumn of 2003 by Christian Reiher and Carlos di Fiore....

Zero-sum problem
In number theory, zero-sum problems are a certain class of combinatorial questions. In general, a finite abelian group G is considered. The zero-sum problem for the integer n is the following: Find the smallest integer k such that every sequence of elements of G with length k contains n terms that...
