The powerpoint slides up to Chapter 2.1 are posted. The typos regarding the commutativity of group actions have been corrected in the earlier lectures (1.2 and possibly 1.3).
We have also uploaded a newer version of the text with updated reading material for next week--in general, we will be doing this periodically throughout the semester, so it would not suffice to just download the PDF once and use it from there. Please check the schedule for the reading assignment.
HW 0 was due today--please submit the online portion if you have not already. At this point, you should also be equipped to start on HW 1, which is due in two weeks.
