Topological semigroup
Summary
A topological semigroup is a semigroup with a topology in which the semigroup operation is jointly continuous. It is a very general setting where algebra and topology meet through one associative operation. Topological monoids and topological groups are special cases. Compact topological semigroups have a rich structure theory with uses in topological dynamics.
