TY - JOUR AU - Luo, Demou PY - 2021 DA - 2021/01/07 TI - Steady state for a predator–prey cross-diffusion system with the Beddington–DeAngelis and Tanner functional response JO - Boundary Value Problems SP - 4 VL - 2021 IS - 1 AB - The main goal of this paper is investigating the existence of nonconstant positive steady states of a linear prey–predator cross-diffusion system with Beddington–DeAngelis and Tanner functional response. An analytical method and fixed point index theory plays a significant role in our main proofs.
