During October 18-21, 2007 I participated in a Dynamical Systems Workshop here at the Pennsylvania State University. I gave a one-hour talk on Degrees of unsolvability of 2-dimensional subshifts of finite type. My abstract is available in several formats: PDF, PS, DVI, HTML, plain text. My slides are available in several formats: PDF, PS.
A list of my recent and upcoming talks is available.
