Basis for a Topology Section Homeomorphisms between topological spaces continuous bijections with continuous inverses , and an example of a continuous bijection that is not a homeomorphism. Homework 8 is due Wednesday, October You can handwrite your solutions, but you are encouraged to consider typing your solutions with LaTeX. The Separation Axioms Section
Homework 8 is due Wednesday, October Submit first draft to Instructor and Viktor. We aim to cover a bit of algebraic topology, e. A function between metric spaces is continuous if and only if the preimage of every open set is open. Sternberg, Dover Publications,
Math 440: Topology, Fall 2017
The instructor strongly adheres to the University policies regarding principles of academic honesty and academic integrity violations, and will strictly enforce these rules. The Integers and the Real Numbers Section 5: You are free to devise whatever strategy for learning the material suits you best. Submit first draft to Instructor and Viktor. A function between metric spaces is continuous if and only if the preimage of every open set is open.
Thursdays pm, in Malott This course covers basic point set topology, in particular, connectedness, compactness, and metric spaces. An introduction to compactness.
We will also study many examples, and see some applications. Sternberg, Dover Publications, There will be some emphasis on material covered since the first exam. Compact Subspaces of the Real Line Section Homework 8 is due Wednesday, October We aim to cover a bit of algebraic topology, e.
Munkres (2000) Topology with Solutions
Below are links to answers and solutions for exercises in the Munkres Topology, Second Edition. A list of some methods for constructing compact subsets: Homework 4 is due Monday, September Covering Spaces Section Continuous functions between metric spaces given using the munkrex definition.
Welcome and overview of class e. The notion of a metrizable topological space. If Y is a subset of X, then the two notions of compactness we’ve discussed for Y as a subset of X, and for Y thought of as asubspace agree.
Images of connected sets under continuous maps are continuous.
Math Introduction to Topology I
If a space is path connected, it is connected too but not munkees vice versa! We will also apply these concepts to surfaces such as the torus, the Klein bottle, and the Moebius band. This syllabus is not a contract, and the Instructor reserves the right to make some changes during the semester.
Textbook Topology2ed, by James R. Examples of metric spaces: The main result we muknres is discussed in Munkres 2. Both exams are closed bookclosed notes exams, with no calculators or other electronic aids permitted. Late homeworks will not be accepted. Quotient maps of sets i.

Continuous Functions Section Basis for a Topology Section Unions of subsets which are each connected in the subspace topology and which have non-empty intersection remain connected. The grading will be based on the homework and the take-home examinations.
Homework 2 is due Wednesday, September 9.
