Abstract
In this paper, we investigate a diffusive predator–prey model with discontinuous harvesting. The model’s boundedness is explored, as well as the presence and stability of equilibria, Hopf bifurcation, and Turing bifurcation. Additionally, we establish the sliding mode’s existence and study different types of sliding mode bifurcation, including boundary node, grazing, buckling, and crossing bifurcation. Additionally, computer simulations demonstrate that the system may develop a variety of spatial patterns depending on the harvesting threshold, the cost of fear, and the initial conditions.
