Explicit propagation reversal bounds for bistable differential equations on trees
Petr Stehlík
In this paper we provide explicit description of the pinning region and propagation reversal phenomenon for the bistable reaction diffusion equation on regular biinfinite trees. In…

Heterogeneous carrying capacities and global extinction in metapopulations
Jakub Hesoun, Petr Stehlík
In this paper we consider a simple two patch reaction diffusion model with strong Allee effect, sufficiently distinct carrying capacities, similar reaction strengths, and strong di…

Traveling Waves in Bistable Reaction-Diffusion Cellular Automata
Daniel Špale, Petr Stehlík
We describe various types of traveling fronts of bistable reaction-diffusion cellular automata. These dynamical systems with discrete time, space, and state spaces can be seen as f…
