Basic Point-Set TopologyOne way to describe the subject of Topology is to say that it isqualitative geom-etry. The idea is that if one geometric object can be continuously transformed intoanother, then the two objects are to be viewed as beingtopologicallythe same.
Notes on Introductory Point-Set Topology Allen Hatcher Chapter 1. ... The Quotient Topology 41, Surfaces 47, Exercises 51. Basic Point-Set Topology 1 Chapter 1. Basic Point-Set Topology ... One of the basic problems of Topology is to determine when two given geometric objects are homeomorphic. This can be quite difficult in general.
