Special Topics:Topology

Topology is the study of properties of objects that remain unchanged when the object is stretched or bent, but not torn. For example, the number of holes in a surface is a topological invarient, as are the number of different kinds of paths around the holes. Some classical objects that are of topological interest are the Klein bottle, and the Moebius band. Current research in topology includes the study of the topology of high-dimensional objects, and of objects in non-Euclidean spaces.
