DSP students should speak to the instructor as soon as possible, even if you don't have a letter yet.

Guidelines on what to do if you think you may have a conflict between this class and your extracurricular activities. In particular, you must speak to the instructor before the end of the second week of classes.

### Textbook

The required text for this course is M.A. Armstrong's *Basic Topology*. It can be downloaded on a campus connection. You may also find *Topology (2*^{nd} edition) by James Munkres helpful, and I suggest it for going deeper.
