Global bifurcation of solutions for a predator-preymodel with prey-taxis

摘要

We study pattern formations in a predator-prey model with prey-taxis. It is proved that a branch of nonconstant solutions can bifurcate from the positive equilibrium only when the chemotactic is repulsive. Furthermore, we find the stable bifurcating solutions near the bifurcation point under suitable conditions. Copyright (c) 2014 John Wiley & Sons, Ltd.
