Global semigroup of conservative solutions of the nonlinear variational wave equation

Helge Holden, Xavier Raynaud

We prove the existence of a global semigroup for conservative solutions of the nonlinear variational wave equation $u_{tt} - c (u) (c (u) u_{x})_{x} = 0$ . We allow for initial data $u ∣_{t = 0}$ …

Operator splitting for the KdV equation

Helge Holden, Kenneth H. Karlsen, Nils Henrik Risebro +1

We provide a new analytical approach to operator splitting for equations of the type $u_{t} = A u + B (u)$ where $A$ is a linear operator and $B$ is quadratic. A particular example is the…

Lipschitz metric for the Hunter-Saxton equation

Alberto Bressan, Helge Holden, Xavier Raynaud

We study stability of solutions of the Cauchy problem for the Hunter-Saxton equation $u_{t} + u u_{x} = \frac{1}{4} (\int_{- \infty}^{x} u_{x}^{2} d x - \int_{x}^{\infty} u_{x}^{2} d x)$ with initial data $u_{0}$ .…

Symmetric waves are traveling waves

Mats Ehrnström, Helge Holden, Xavier Raynaud

We show that horizontally symmetric water waves are traveling waves. The result is valid for the Euler equations, and is based on a general principle that applies to a large class…
