Dear **anyone in PMATH 764**: if you have notes for Monday and Wednesday of this week (i.e. March 26 and 28), handwritten or typed, your contribution of them would cause my pmath764notes.pdf to be 100% complete, and would therefore be greatly appreciated by not only myself, but also surely by a great many others. Please contact me at the email address provided on the About page. I will certainly credit you. Cheers.

**EDIT**: Thanks to two anonymous contributors (maybe now with two sets of the same notes, I may have a lone chance in hell of making heads or tails of this! ah, I kid). Next blog post is on exact sequences and their connections to (semi)direct products of groups and so on — this may or may not completely derail into a category theory post.

just another guy trying to make the diagrams commute.

I am not sure whether or not you know this, but there is an assignment due tomorrow. The assignment questions from the book are chapter 5 number 18,21,25,26,30

LOL

hey was the last day of pmath346 March 30th (or are you missing that day in your notes)? Thanks.

The last day was April 2. I updated the notes, but my notes for that day are sub-par. I’ll try to fix them up soon, but I’m busy studying for other exams too.
