On probabilistic ill-posedness

Tadahiro Oh, Nikolay Tzvetkov

In this note, we introduce an enhanced notion of probabilistic well-posedness for dispersive PDEs with random initial data by imposing stability at the origin as the amplitude of r…

Hyperbolic -model on the plane

Tadahiro Oh, Leonardo Tolomeo, Yuzhao Wang +1

We study the hyperbolic -model on the plane. By establishing coming down from infinity for the associated stochastic nonlinear heat equation (SNLH) on the plane, we fir…

On the deep-water and shallow-water limits of the intermediate long wave equation from a statistical viewpoint

Guopeng Li, Tadahiro Oh, Guangqu Zheng

(Due to the limit on the number of characters for an abstract set by arXiv, the full abstract can not be displayed here. See the abstract in the paper.) We study convergence proble…

Norm inflation for the cubic nonlinear heat equation above the scaling critical regularity

Ilya Chevyrev, Tadahiro Oh, Yuzhao Wang

We consider the ill-posedness issue for the cubic nonlinear heat equation and prove norm inflation with infinite loss of regularity in the Hölder-Besov space $\mathcal C^s = B^{s}…

Stochastic quantization of the -model

Tadahiro Oh, Mamoru Okamoto, Leonardo Tolomeo

(Due to the limit on the number of characters for an abstract set by arXiv, the full abstract can not be displayed here. See the abstract in the paper.) We study the construction o…

Focusing -model with a Hartree-type nonlinearity

Tadahiro Oh, Mamoru Okamoto, Leonardo Tolomeo

(Due to the limit on the number of characters for an abstract set by arXiv, the full abstract can not be displayed here. See the abstract in the paper.) Lebowitz, Rose, and Speer (…
