On the Radius of Analyticity for a Korteweg-de Vries-Kawahara Equation with a Weakly Damping Term
Aissa Boukarou, Daniel Oliveira da Silva
We consider the Cauchy problem for an equation of Korteweg-de Vries-Kawahara type with initial data in the analytic Gevrey spaces. By using linear, bilinear and trilinear estimates…
Habitat fragmentation: the possibility of a patch disrupting its neighbor
Daniel Juliano Pamplona da Silva, Edmundo Capelas de Oliveira
This paper starts from the Fisher-Kolmogorov-Petrovskii-Piskunov equation to model diffusive populations. The main result, according to this model, is that two connected patches in…
Crossing-effect in non-isolated and non-symmetric systems of patches
Daniel Juliano Pamplona da Silva
The main result of this article is the determination of the minimal size for the general case of problems with two identical patches. This solution is presented in the explicit for…
Isolation effects in a system of two mutually communicating identical patches
Daniel Juliano Pamplona da Silva, Renato Pacheco Villar, Lorielen Calixto Ramos
Starting from the Fisher-Kolmogorov-Petrovskii-Piskunov equation (FKPP) we model the dynamic of a diffusive system with two mutually communicating identical patches and isolated of…
