Topology (2nd edition - Pearson - Classic Version 2018) by J. Munkres. ISBN-10 9780134689517.

Any other version of the texbook should work.


These are strict prerequisites,

  • (MATH 171 - MATH 174) or (MATH 161 - MATH 162).
  • MATH 200 or MATH 235.
  • Permission of instructor.


Weekly homework will be posted on the course page and collected through Gradescope. You are encouraged to work with other students on the homework problems, but you must write up and submit your own solutions. The two lowest homework scores will be dropped. Late homework will only be accepted with prior arrangements and/or due to exceptional circumstances.

Getting Help

In addition to regularly attending class, you are strongly encouraged to come to office hours. No appointment is necessary to come to office hours — just drop in! You are welcome collaborate with your classmates (although all work you turn in must be your own!). Use the Blackboard forum to connect with the instructor or TA for help anytime outside office hours!

Finally, some strategies students at UR found successful include the following:

  • Always go to class and take good notes.
  • Review your notes soon after class — within the next day or so!
  • Read (or at least skim) each section in the text before it is covered in class.
  • Do all of the homework thoroughly, write out all of the details, keep it organized, and use it to help you study.
  • If you don’t understand something, ask right away.
  • Go over tests and look at solutions until you know what you did wrong and understand the solution.
  • Figure things out rather than memorize them.
  • Arrange your schedule so that you have enough time every week to study and do homework.
  • Start studying for exams early.
  • Get plenty of rest the night before an exam.
  • Don’t stress out and don’t give up!
