Kate Ponto
Fall 2013

### Announcements

My office hours are now Monday, Tuesday, and Wednesday 3-3:50.

Make sure you check the assigned homework frequently! There will usually be problems assigned everyday - so if you check on Monday be sure to check back - there might be more problems added on Wednesday and Friday.

The syllabus for the course.

The textbook for this course will be

Introduction to Topology: Pure and Applied by Colin Adams and Robert Franzosa (ISBN: 0131848690)

It is sometimes helpful to have another textbook with a slightly different perspective. A good choice is

Introduction to Topology: Third Edition (Dover Books on Mathematics) by Bert Mendelson (ISBN: 0486663523)

The book by Mendelson is not required for the course.
