In the limit \(N\to\infty\) with \(s=1.4\) and without mutations, \(\mu=0\), \(\hat x\) is an attractor of the replicator dynamics. The figure shows a sample trajectory that spirals towards the interior fixed point \(\hat x\).
In the limit \(N\to\infty\) demographic stochasticity arising in finite populations disappears and the dynamics becomes deterministic. For \(s>1\) the interior fixed point \(\hat x\) is a stable focus of the replicator dynamics. All trajectories spiral toward \(\hat x\).
