Abstract:
We investigate the long-time dynamics of a two-species competition model of Lotka Volterra type with nonlocal diffusions. In this setting, a native species occupies the whole environment, while an invading species spreads with two moving fronts, forming a habitat that expands over time. The system is modeled by a reaction diffusion equation with free boundaries, and the key question is whether the invaded region eventually remains bounded or grows without limit.
