Nature and number of fixed points of replicator dynamics. Given the definition of ${\lambda }^{*}=R(M/N)$, we identify the fixed points of the replicator dynamics, as well as their nature, for the different regimes associated with the possible values of the ratio F/N. Besides the trivial endpoints {0,1}, we also identify possible interior fixed points {x_L, x_R} satisfying $x_{\text{L}}\in (0,M/N)$ and $x_{\text{R}}\in (M/N,1)$ (see main text for additional details).
