Generic regularity and Lipschitz metric for a two-component Novikov system

Kenneth H. Karlsen, Yan Rybalko

We investigate the Cauchy problem for a two-component generalization of the Novikov equation with cubic nonlinearity -- an integrable system whose solutions may develop strong nonl…

Yamada-Watanabe uniqueness results for SPDEs driven by Wiener and pure jump processes

Kistosil Fahim, Erika Hausenblas, Kenneth H. Karlsen

The Yamada-Watanabe theory provides a robust framework for understanding stochastic equations driven by Wiener processes. Despite its comprehensive treatment in the literature, the…

On the well-posedness of the Cauchy problem for the two-component peakon system in

Kenneth H. Karlsen, Yan Rybalko

This study focuses on the Cauchy problem associated with the two-component peakon system featuring a cubic nonlinearity, constrained to the class $(m,n)\in C^{k}(\mathbb{R}) \cap W…

On the well-posedness of a nonlocal (two-place) FORQ equation via a two-component peakon system

Kenneth Karlsen, Yan Rybalko

We investigate the Cauchy problem for a nonlocal (two-place) FORQ equation. By interpreting this equation as a special case of a two-component peakon system (exhibiting a cubic non…

A convergent finite difference method for a nonlinear variational wave equation

H. Holden, K. H. Karlsen, N. H. Risebro

We establish rigorously convergence of a semi-discrete upwind scheme for the nonlinear variational wave equation with and $u_t|_{t=0}…
