Notes on Introductory Point-Set Topologysuch as spheres and polyhedra become topological spaces, with the subspace topology from the usual topology on RBasic PointSet Topology
Basic Point-Set Topology 3 means that f(x) is not in O. On the other hand, x 0 was in f −1 (O) so f(x 0 ) is in O. Since O was assumed to be open, there is an interval (c, d) about f(x 0 ) that is contained in O. The points f(x) that are not in O are...

General Topology (Pete L. Clark) This is an oustanding book on introductory topology (point set topology). The book is short. However, it is solid and complete and the proofs presented by the author are surprisingly optimised: very concise but always clear. Topological Groups: Yesterday, To...
