Syllabus for MAT 622 - Topology
Credits
(Lec:Tut:Lab): 3:1:0
(3 lectures and 1 tutorial weekly)
Prerequisites:
MAT
220 (Real Analysis) or equivalent
Overview:
This
course concerns 'General Topology' which can be characterized as the
abstract framework in which the notion of continuity can be framed
and studied. Thus topology provides the basic language and structure
for a large part of pure and applied mathematics.
We
will take up the following topics: Open and closed sets, continuous
functions, subspaces, product and quotient topologies, connected and
path connected spaces, compact and locally compact spaces, Baire
category theorem, separability axioms.
Detailed
Syllabus:
- Review: Operations with infinite collections of sets, axiom of choice, Zorn's lemma, real line, metric spaces.
- Topological Spaces: Definition and examples of topological spaces, Hausdorff property, fine and coarse topologies, subspace topology, closed sets, continuous functions, homeomorphisms, pasting lemma, product topology, quotient topology.
- Connectedness and Compactness: Connected spaces and subsets, path connectedness, compact spaces and subsets, tube lemma, Tychonoff theorem, local compactness, one-point compactification, Baire category theorem.
- Separation Axioms: First and second countability, separability, separation axioms (T1 etc.), normal spaces, Urysohn lemma, Tietze extension theorem.
- Topics for Student Presentations: Order topology, quotients of the square, locally (path) connected spaces, sequential and limit point compactness, topological groups, nets, applications of Baire category theorem.
