National University of Singapore, July-August 2005

I am Stephen G. Simpson, a mathematician at the Pennsylvania State University.

During July 21 - August 11, 2005, I was at the Institute for Mathematical Sciences of the National University of Singapore. I attended a workshop on Recursion Theory, part of a program on Computational Prospects of Infinity. On August 4 and August 8, I gave two invited one-hour talks, one on reverse mathematics and the other on degrees of unsolvability.

A list of my recent and upcoming talks is available.

My publication list is available. / 24 August 2006
