DYNAMICS OF A HOST-PATHOGEN SYSTEM ON A BOUNDED SPATIAL DOMAIN

Abstract. We study a host-pathogen system in a bounded spatial habitat where the environment is closed. Extinction and persistence of the disease are investigated by appealing to theories of monotone dynamical systems and uniform persistence. We also carry out a bifurcation analysis for steady state solutions, and the results suggest that a backward bifurcation may occur when the parameters in the system are spatially dependent. 1.
