consider a known predator-prey system, where more than one predator compete for the same prey. Mainly the case with two predators is
considered. A review of general results is given, among them conditions
for the extinction of one predator and an investigation of the different
types of coexistence of predators. In non-degenerate cases the predators
in this model cannot coexist at an equilibrium, but there can be a
cyclic or more complicated coexistence. Many numerical results are
presented. A model map for a Poincar´e map is given under some
conditions. But the most interesting case where there can arise
”spiral-like” attractors is not well known here, and we pose open
questions. We discuss some bifurcations and the existence of systems
with several attractors.
