An Introduction to the Structure Theory. Additive subsemigroups of N and Nn have close ties to algebraic geometry. By the structure of finite commutative semigroups was fairly well understood. Archimedean decompositions, a comparatively small part oftoday’s arsenal, have been generalized extensively, as shown for instance in the upcoming books by Nagy [] and Ciric [].
