Also known as associative magma
In mathematics, a semigroup is an algebraic structure consisting of a set together with an associative internal binary operation on it. In mathematical analysis, the term also appears in the theory of one-parameter operator semigroups: see C0-semigroup.

在数学中，半群是闭合于结合性二元运算之下的集合 S 构成的代数结构。 半群的运算经常指示为乘号，也就是 或简写为 xy 来指示应用半群运算于有序对 (x, y) 的结果。 半群的正式研究开始于二十世纪早期。自从1950年代，有限半群的研究在理论计算机科学中变得特别重要，因为在有限半群和有限自动机之间有自然的联系。
