The Rest is Left too…

Often when studying an area of mathematics we encounter proofs that are either too short, too technical for their placement in the book, or completely absent. As a result, we find ourselves a little lost in the woods, and sometimes it is not clear how to find a good way out. Gone are the days when the back of the book can come to the rescue, and gone are the days when you can call up a friend (unless your friend is a homological algebraist, which is impossible, since we do not have any friends) and ask for assistance. This website is my small attempt to be the back of the book and to be that friend. Using my free time (truly a laughable amount) I take lemmas and theorems from sources on homological algebra, and related fields and prove the results in a longer format. Right now, there are very few that are ready, but I hope for you to enjoy the ones that are there. Each problem will be sorted by the book it was taken from, and by the chapter in which it appears. If you have any suggestions that you think could improve a specific proof or the website in general, you should wonder when I asked! Kidding, of course, please use the resources to contact me anytime, this website is a work in progress, and as such, has many things that no doubt can be improved.
But, without further ado, except for this bit of ado that I’ll add here for style points, let’s begin.
