Approximating basins of attraction for dynamical systems via stable radial bases
For researchers modeling multi-stable dynamical systems in applied sciences, this provides a new approximation technique for basins of attraction.
This paper proposes a method to approximate basins of attraction for multi-stable dynamical systems using stable radial basis functions, applied to a competition model with three stable equilibria.
In applied sciences, such as physics and biology, it is often required to model the evolution of populations via dynamical systems. In this paper, we focus on the problem of approximating the basins of attraction of such models in case of multi-stability. We propose to reconstruct the domains of attraction via an implicit interpolant using stable radial bases, obtaining the surfaces by partitioning the phase space into disjoint regions. An application to a competition model presenting jointly three stable equilibria is considered.
