I've made a small organizational change to this blog. I realize it might not have been easy to find series of posts on one topic, or the "post series". They used to be on a page called "features" but I think that was too obscure. Now there's the page "post series", which is found above on the header. Along with the current series I have going on Non-unique Factorisation, it also lists five posts on Waldhausen categories.
Perhaps the most exciting in my mind is the six posts of "Wild Spectral Sequences", which give little toy problems that can be solved using spectral sequences. I came up with all the proofs myself, and some of them might be published nowhere else. Though I admit some of them are quite basic, I think they are quite instructive!
