In mathematics, a semigroup is an algebraic structure consisting of a
|
|
set together with an associative binary operation. A semigroup
|
|
generalizes a monoid in that there might not exist an identity element.
|
|
It also (originally) generalized a group (a monoid with all inverses) to
|
|
a type where every element did not have to have an inverse, thus the
|
|
name semigroup.
