…and this lead him to the Gause <strong>model</strong>…<br />

dR<br />

dt<br />

= rR−Cf(R)<br />

dC<br />

dt<br />

= (ef(R)−m)C<br />

Gause‘s stability criterion: Let (R ∗ , C ∗ ) be an equilibrium of the above <strong>model</strong>.<br />

Provided<br />

df<br />

dR (R∗ ) > f(R∗ )<br />

R ∗<br />

then the equilibrium is locally asymptotically stable.<br />
