Abstract
The Monoid M(X) of homology classes of effective cycles of codimension 1 on an n-dimensional complex torus X is characterized in terms of 2n × 2n integer matrices. Examples of tori X are constructed for which M(X) is finitely generated, as well as examples for which finite generation fails. In particular, it is shown that for "general" products X of elliptic curves, M(X) is finitely generated, while for Abelian varieties of the singular type, finite generation of the monoid fails.
