After an almost year long hiatus I am getting back into math blogging. The new address is a bit long but at least easy to remember! (turns out “pdeblog.wordpress.com” was already taken!), please update your bookmarks!
The old site (the one you are looking at now) will be up at least for a while, but all the old posts have been copied to the new blog, To reflect the fact that nearly all posts here have dealt with Partial Differential Equations the new site will go by the name “PDE Blog”.
