You may have noticed that this blog has not been updated in several months. I thought I should announce that I will no longer be updating and/or maintaining this blog (this includes responding to comments). For the time being the content on this site will remain available, but that may change. I’m mulling the idea of creating a new blog more relevant to my graduate studies and interests (harmonic analysis, pde, etc.), which would be at a higher technical level. But nothing is in the works at this time. One final time, I thank you all for your readership.
