This Saturday I am presenting a talk on the role of path algebras in quantum causal theory at the Conference on Ordered Algebraic Structures at Louisiana State University.
Below are my slides:
Path Algebras in Quantum Causal Theory
The slides have a lot of nice graphics, and even if some of the material is unfamiliar, they should give you a nice overview of what quantum causal theory is about.
You’d be hard-pressed to find another half-hour math talk with Newton, Cauchy, Riemann, Einstein, Schrödinger, Wheeler, Feynman, Grothendieck, Hawking, Sorkin, Connes, and Malament in it!
