MUNKRES TOPOLOGY HOMEWORK

There will be some emphasis on material covered since the first exam. Future topics are tentative and will be adjusted as necessary. Homework 7 is due Monday, October In complete generality, compactness and sequential compactness both imply limit point compactness, but compactness and sequential compactness are not equivalent and one doesn’t imply the other. It is recommended that you take at least one other upper level mathematics course before Math i.

Closed sets, and first examples. Chapter 1 Section 1: Unions of subsets which are each connected in the subspace topology and which have non-empty intersection remain connected. Sequences in sets are defined in Munkres p. Homework 9 half weight. Examples of quotient maps of sets coming from partitions , which in turn are often sets of equivalence classes under an equivalence relation.

Homework 8 munjres due Wednesday, October Continuous Functions Section Sequences and convergent sequences in a metric space. Other notions of compactness: Infinite Sets and the Axiom of Choice Section Clark Fractals and Self Similarity by J.

A more detailed lecture plan updated on an ongoing basis, after each lecture will be posted below. Students are not allowed to work together on these.

Retractions and Fixed Points Section This means you should try to use complete sentences, insert explanations, and err on the side of writing out “for all” and “there exist”, etc. The interior of a set. Homework Homework 1 is due Monday, August Normal Spaces Section Examples of metric spaces: In complete generality, compactness and sequential compactness both imply limit point compactness, but compactness and sequential compactness are not equivalent and one doesn’t imply the other.
