## INTRODUCTORY TOPOLOGY

### Assignments

Multiple-page homework must be STAPLED when handed in.

Note: In some problems you are asked to determine whether or not something is true; you are expected to justify your answer. An affirmative answer requires a proof; a negative answer is usually best supported by a counterexample. Similarly, if you are asked to describe something, or any similar question, the answer must be justified.
