Paratopological group
In mathematics, a paratopological group is a topological semigroup that is algebraically a group.〔Artur Hideyuki Tomita. (On sequentially compact both-sides cancellative semigroups with sequentially continuous addition. )〕 In other words, it is a group ''G'' with a topology such that the group's product operation is a continuous function from ''G'' × ''G'' to ''G''. This differs from the definition of a topological group in that the group inverse is not required to be continuous.
As with topological groups, some authors require the topology to be Hausdorff.〔A. V. Arhangelskii. (Topological spaces connected to algebraic structures )〕
Compact paratopological groups are automatically topological groups.
