Boundary effects in the λ-phage. (Left) Nullclines and flow field in the phase diagram of the λ-switch. There is a fixed point corresponding to the lytic phase, but no clear fixed point corresponding to lysogeny. (Right) Probability distributions of cro around extinction, showing that border effects can guarantee stability of lysogeny at high concentrations of repressor. At lower concentrations of repressor, lysogeny is no longer stable.
