- 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.
