Remarks on Spreading and Vanishing for Free Boundary Problems of Some Reaction-Diffusion Equations

We discuss a free boundary problem for a diffusion equation in a one-dimensional interval which models the spreading of invasive or new species. Moreover, the free boundary represents a spreading front of the species and its dynamical behavior is determined by a Stefan-like condition. This problem h...
