| Abstract: | This paper introduces a method of localization of Abclian addition semigroups, considers the relation between the localization and the tensor product and proves that the localization of flat semigroup is also flat. This paper proves also the localization functor is exact covariant which is naturally equivalent to an one-sided tensor product functor. |
