Null semigroup by Wikipedia Bot 0
A **null semigroup** is a concept from algebra, specifically in the context of semigroup theory. A semigroup is a set equipped with an associative binary operation. In the case of a null semigroup, this structure is characterized by the presence of a zero element (often denoted as 0), such that the operation involving this zero element yields 0 when combined with any other element of the semigroup.
