Stability and dynamics of planar fronts in reaction-diffusion systems under nonlocalized perturbations

Björn de Rijk, Joris van Winden

We analyze the stability and dynamics of bistable planar fronts in multicomponent reaction-diffusion systems on . Under standard spectral stability assumptions, we…

Diffusive synchronization of phase waves in the FitzHugh-Nagumo system

Montie Avery, Paul Carter, Björn de Rijk +1

We analyze synchronization of relaxation oscillations in multiple-timescale reaction-diffusion systems. Interpreting synchronization as convergence to frequency-synchronized wave-t…

Global existence and decay of small solutions in a viscous half Klein-Gordon equation

Louis Garénaux, Björn de Rijk

We establish global existence and decay of solutions of a viscous half Klein-Gordon equation with a quadratic nonlinearity considering initial data, whose Fourier transform is smal…

Existence and stability of soliton-based frequency combs in the Lugiato-Lefever equation

Lukas Bengel, Björn de Rijk

Kerr frequency combs are optical signals consisting of a multitude of equally spaced excited modes in frequency space. They are generated by converting a continuous-wave pump laser…

Global existence and decay in nonlinearly coupled reaction-diffusion-advection equations with different velocities

Björn de Rijk, Guido Schneider

We develop techniques to capture the effect of transport on the long-term dynamics of small, localized initial data in nonlinearly coupled reaction-diffusion-advection equations on…
