TITLEOn a Nonlocal PDE from Conservation Biology

ABSTRACT In this talk we shall discuss a mathematical model from conservation biology for the survival of the species of big-size mammals in a forest. The model takes a form of nonlocal PDE of parabolic type. We study the corresponding elliptic problem, the existence of positive solutions and its multiplicity. We use the techniques of bifurcation from simple eigenvalues and Rabinowitz global bifurcation.
