Invariant Gibbs measures for the three dimensional cubic nonlinear wave equation

B Bringmann, Y Deng, AR Nahmod, H Yue - Inventiones mathematicae, 2024 - Springer
We prove the invariance of the Gibbs measure under the dynamics of the three-dimensional
cubic wave equation, which is also known as the hyperbolic Φ 3 4-model. This result is the …
