Previous: Instead of Classnotes
Required email. The class photo will be on the class' web site in a day or two and you are all required to find it, find yourself in the photo, and send me an email message (either using the feedback form on the class' web site or using my regular email address) with the following information:
Your email is due earlier than the rest of this assignment, on Monday October 4 at 4PM. If you aren't in the picture at all, find me before Monday and I'll take a (small) picture of you on the spot and edit it into the main picture.
Required reading. Read, reread and rereread your notes to this point, and make sure that you really, really really, really really really understand everything in them. Do the same every week! Also, read all of Munkres chapter 2.
Solve the following problems. (But submit only the underlined ones). In Munkres' book (Topology, 2nd edition), problems 4, 8 on pages 83-84, problems 4, 8 on page 92, problems 6, 7, 13 on page 101, problems 9, 11, 12, 13 on page 112, problems 6, 7 on page 118 and problems 3, 8 on pages 126-128. Also solve (but don't submit) the following
Problem. Let be the ``Cantor set'', the closure of the set of real numbers in whose expansion to base 3 doesn't contain the digit (e.g., is in, but is out). Prove that (taken with the topology induced from ) is homeomorphic to (taken with the product topology).
