Random thoughts on my classes, teaching, research and life. September 21, 2011 in Math. As mentioned in the previous post, here is the algebra qual with my solutions.

I think my only mistake came on problem 5(a), I gave a pretty hand wavy argument. Oh well…. Is a homomorphism if and only if. Is a homomorphism. Let. Multiplying on the left by.

Random thoughts on my classes, teaching, research and life. Summer, quals, school,…. September 19, 2011 in Life. I haven’t posted anything in a while. The first half of summer was fun; the second half, stressful! As you may know from previous posts, I spent the first few weeks of summer in Europe. AMAZING! I got back to California the beginning of July. I had some friends visit, I visited some friends; all in all, July and the first half of August were fun. I need to take one more class ( Galois theory.
