Large saturation effects provoke multiplicity in spatially heterogeneous predator-prey models. Prensas de la Universidad de Zaragoza Zaragoza. 2023, pp. 31-38.978-84-18321-66-5https://hdl.handle.net/20.500.14352/134541This communication analyzes the diffusive spatially heterogeneous predator-prey model introduced by the authors in [16], which takes into account the saturation effects of the predator in the abundance of preys through a saturation coefficient $\gamma m(x)\neq0$ with $\|m\|_{\infty}=1$. The main result establishes the existence of, at least, two coexistence states for sufficiently large $\gamma>0$ in a region of the parameters where the Lotka–Volterra counterpart cannot admit any coexistence state, regardless the size and shapes of the logistic and interactions coefficients of the model.engLarge saturation effects provoke multiplicity in spatially heterogeneous predator-prey modelsconference paper10.26754/uz.978-84-18321-66-5open access517.9Ecuaciones diferencialesEcuaciones diferenciales1202.20 Ecuaciones Diferenciales en derivadas Parciales
