Spectral scheme for an energetic Fokker-Planck equation with $I^º$ -distribution steady states

Claudia Negulescu, Hugo Parada

The concern of the present paper is the design of efficient numerical schemes for a specific Fokker-Planck equation describing the dynamics of energetic particles occurring in ther…

On regularity and rigidity of $2 \times 2$ differential inclusions into non-elliptic curves

Xavier Lamy, Andrew Lorent, Guanying Peng

We study differential inclusions $D u \in I^$ in an open set $I^c ◯ \subset R^{2}$ , where $I^\subset R^{2 \times 2}$ is a compact connected $C^{2}$ curve without rank-one conne…

Orbital stability of plane waves in the Klein-Gordon equation against localized perturbations

We investigate the stability and long-term behavior of spatially periodic plane waves in the complex Klein-Gordon equation under localized perturbations. Such perturbations render…
