This schedule is, as the title indicates, tentative. It is updated up to (and including) the homework due the next week but future assignments may be modified if the progress of the class requires it. It is your responsibility to check it weekly.

Homework is a mandatory part of the course. Homework assignments are due each week at the beginning of the Monday's class. Under no circumstances will late homework be accepted. 

The numbering in the schedule below refer to the course textbook Introduction to Topology, pure and applied by Colin Adams and Robert Franzosa.  The extra-credit homework (denoted by EC in the schedule below) is optional but you are encouraged to work on them.

It is allowed (and encouraged) to discuss the problems with other students in the class, however you (and only you and nobody else but you) are responsible for the write up. All the work you hand in should be your own, not copied from someone else  work. You should list all your sources and collaborators.  Suspiciously similar solutions will receive no credit and will be reported to the Academic Judiciary.

New material is presented every week. You should read the corresponding section of the textbook before the class.
