Arithmetic and Ideal Theory of Commutative Semigroups

Annals of Mathematics, 1938
A set S in which a multiplication ab is defined is called a semigroup if this multiplication is associative and commutative, if an identity element is present in S, and if the cancellation law holds: ab = ac implies b = c. For example, the non-zero elements of a domain of integrity constitute a semigroup under multiplication.
