Welcome

I will be sabbatical for 2007-2008, at the University of Michigan and at the Institute for Advanced Study. 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.
