I just heard about this from George Sparling, who is giving a talk this afternoon with the title “From Roger Penrose to Robert Langlands and back” at a symposium in Pittsburgh. I don’t at all know what this is about, but am posting this quickly because he tells me there may be a live stream of his talk at 5pm today, available at
Evidently yesterday and today at Pittsburgh there’s a symposium on “Towards the Unification of Mathematics and Physics”, with the following schedule:
4pm Wednesday: Mellon Professor Thomas Hales, “The present status of the Langlands Conjecture”.
5pm Wednesday: Jonathan Holland, “Parabolic geometry”.
4pm Thursday: Tim Adamo, University of Oxford, “Twistor-String theory and gravity”
5pm Thursday: George Sparling, “From Roger Penrose to Robert Langlands and back.”
Last week there was a workshop at Banff on The Geometry of Scattering Amplitudes, with videos now available. I’ll try soon to take a look at some of them, Sparling’s may give an idea of what he is up to.
And, for something completely different, see this interview with Edward Frenkel about the Langlands Program at the Fields Institute blog for this fall’s Fields Medal symposium.
Update: There’s a video of the Sparling talk available here.
