Much of topology is
aimed at exploring abstract versions of geometrical objects in our world. The
concept of geometrical abstraction dates back at least to the time of Euclid.
All of the objects that we will study in this note will be subsets of the
Euclidean spaces. Topics covered includes: 2-manifolds, Fundamental group and
covering spaces, Homology, Point-Set Topology, Group Theory, Graph Theory and
The Jordan Curve Theorem.
