The renormalized wave equation with quadratic nonlinearity and additive white noise in 3d

  • Herbert Koch (Universität Bonn)
A3 01 (Sophus-Lie room)


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.
