Introduction into regularity structures

  • Lecturer: Felix Otto
  • Date: Wednesday, only at 24.10., 07.11., 5.12., 19.12., 16.01., 30.01.
  • Time: 09:15 - 11:00
  • Room:  A3 01
  • Language: English
  • Target audience: MSc students, PhD students, Postdocs
  • Remarks:  I will follow Hairer’s lecture notes “Regularity structures and the dynamical Phi-4-3 model”, and expand on my mini-course given at the Newton institute.


I will give an introduction into the notions and tools of regularity structures, which were developed to renormalize the nonlinearity in partial differential equations driven by white noise. I will discuss these tools when applied to (a proxy for) the dynamical Phi-4-3 model. This model amounts to an Allen Cahn equation driven by space-time white noise for analysts, or to the stochastic quantization in quantum field theory for math physicists.
