This blog will supplement (but not replace) the webpages of the courses which I teach. There are many interesting things related to the course material that I’d like to talk about in the class but am unable to because of time constraints. This blog will hopefully fill that gap. From time to time, I will also post on general mathematics topics (i.e. not related to the courses I am teaching) which I find interesting. This project is in its infancy so the finished version may look different from what you see now. I welcome comments, suggestions and participation from readers.
