DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nmps/1/">Ove
 rview of Classical and Quantum Integrability in Four Dimensions</a>\nby Ro
 land Bittleston (Perimeter Institute) as part of Nagoya Math-Phys Seminar\
 n\n\nAbstract\nThis talk will review recent progress by a number of groups
  in understanding classical and quantum integrable models in four dimensio
 ns. This has been achieved by exploiting twistor methods. After a short in
 troduction to twistors\, I will introduce some of the simplest examples of
  4d theories with twistor uplifts: self-dual Yang-Mills and the 4d WZW mod
 el. I then plan to touch on a number of topics including: the connection t
 o 4d Chern-Simons theory\, quantization of these theories on twistor space
 \, their hidden symmetry algebras (also known as celestial chiral algebras
 ) and finally the twistor string.\n
