My office mate Sarp Akcay recently gave a nice public talk on “Black Holes: from a mathematical curiosity to Hollywood blockbuster” as part of the Pint of Science festival. Check it out to get an idea of the kind of research our group is interested in.
On Tuesday, March 24 2015 I gave a talk at Perimeter Institute in Waterloo, Canada. In the presentation, I described xAct, a tensor algebra package for Mathematica which was primarily developed by Jose Maria Martin-Garcia. The talk is available online through the Perimeter Institute video library and the Mathematica notebook containing the slides from the talk are available for download separately.
