In mathematics, general topology or point-set topology is the branch of topology which studies properties of topological spaces and structures defined on them. It is distinct from other branches of topology in that the topological spaces may be very general, and do not have to be at all similar to manifolds. General topology provides the most general framework where fundamental concepts of topology such as open/closed sets, continuity, interior/exterior/boundary points, and limit points could be defined.

“In general I do not draw well with literary men—not that I dislike them but I never know what to say to them after I have praised their last publication.”
—George Gordon Noel Byron (1788–1824)
