Global bifurcation of coexistence states for a prey-taxis system with Dirichlet conditions

Shanbing Li, Mingxin Wang

This paper is concerned with positive solutions of boundary value problems \begin{equation*} \left\{\begin{array}{ll} {\rm div}\left(d(v)\nabla u-uχ(v)\nabla v\right)+λu-u^2 +γu F(…
