Welcome

This semester I am teaching M380C (first semester graduate algebra). I have put online my CV and list of publications. At times the publication list is slightly dated; here are the publications themselves. At the bottom of the page there are also some expository notes. Please email me at allcock at math.utexas.edu if you have trouble downloading, printing or understanding my papers.
