### Bjoern Bringmann, IAS – Analysis & PDE Seminar

Speaker: Bjoern Bringmann. Title: Invariant Gibbs measures for the three-dimensional cubic nonlinear wave equation. Abstract: In this talk, we prove the invariance of the Gibbs measure for the three-dimensional cubic nonlinear wave equation, which is also known as the hyperbolic Φ43-model. This result is the hyperbolic counterpart to seminal works on the parabolic Φ43-model by Hairer ’14 and Hairer-Matetski ’18. In the rst half of this talk, we illustrate Gibbs measures in the context of Hamiltonian ODEs, which serve as…
