Cool QFT Links

Matilde Marcolli provides links to You Tube lectures on QFT by Alain Connes and herself. Meanwhile Carl Brannen continues his series of posts on snuarks in QFT. Thanks to David Speyer, here is an interesting paper on lattice congruences and Hopf algebras.

Warning: The first Marcolli lecture begins with Lagrangian densities and actions and it isn’t possible (at least on my monitor) to see the blackboard or overheads clearly. The first Connes lecture is a bit easier to see and an outstanding overview of the situation in renormalisation theory.

    thank you for the links. I looked the first lecture of Alain Connes having as a background attempt to understand a couple of papers about the topic. He is really a master in explaining the big picture. Thank for God or Whoever it was who gave us Youtube (and Alain Connes)!

    In the second lecture of Connes the picture was paralyzed periodically. Sound quality was also poor. Sad.

    You’re ahead of me! Hopefully I’ll get to the second lectures today.
