Abstract

The dynamics of a non-Volterra cubic stochastic operator on the two-dimensional simplex are analyzed. All of its fixed points and 2-periodic orbits are identified. It is shown that, depending on the initial state, the trajectories either converge to a unique 2-periodic cycle or stay near a repelling equilibrium. The effectiveness of the theoretical findings is illustrated through numerical examples.
