  • Date : 17 Jul. (Thu)
  • Place: W.W. 7th-floor, 3rd lab. 
  • Time : 16:30 – 18:00
  • Speaker: Tomoki Shibutani (Ritsumeikan University)
  • Title: Noises and Its Spectral Measures.
  • Abstract: Along the line of the survey by Akahori, Izumi and Watanabe, I will talk about the theory of noises introduced by Tsirelson. As examples, white noises and Poisson noises are found to be classical in this framework. To discuss beyond the classical noises, we will see a theorem obtained by Tsirelson, which is used to introduce the spectral measure for a given noise. With this equipment, the notion of the classical homogeneous Wiener chaos appears to have the first order generalization in nonclassical cases, which is called superchaos. As extremal objects, black noises are defined.
