| 11. | In other words, a monoid is a semigroup with an identity element.
|
| 12. | However, not every monoid sits inside a group.
|
| 13. | A semigroup homomorphism between monoids preserves identity if it is a monoid homomorphism.
|
| 14. | Particularly, if f is surjective, then it is a monoid homomorphism.
|
| 15. | However this quotient itself is generally only a monoid.
|
| 16. | Those axioms are formally similar to the monoid axioms.
|
| 17. | A civil war erupts between the two Monoid factions.
|
| 18. | An abstract mathematical foundation for synchronization primitives is given by the history monoid.
|
| 19. | The collection of functions f _ i together with composition form a monoid.
|
| 20. | Since the monoid is finite, for some.
