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.
