Oberseminar ANALYSIS - PROBABILITY

Herbert Koch (Universität Bonn)
The renormalized wave equation with quadratic nonlinearity and additive white noise in 3d

In this joint work with Massimilano Gubinelli and Hiro Oh we prove local wellposedness for a renormalized wave equation with additive white noise. Key ingredients are an ansatz going back to Da Prato and Debussche, a paraproduct decomposition, and an analysis of various stochastic fields and of a stochastic operator.
