Graphing nullclines

WebJul 17, 2024 · The trivial fixed point ( 0, 0) is unstable since the prey population grows exponentially if it is initially small. To determine the stability of the second fixed point, we write the Lotka-Volterra equation in the form. d U d t = F ( U, V), d V d t = G ( U, V) with. F ( U, V) = α U − γ U V, G ( U, V) = e γ U V − β V. Webxlim.
