The solid curves show the theoretical mean-field prediction for the boundaries of the bi-stability region,
and

. The dashed lines and circles show the corresponding boundaries computed by solving the Markovian evolution equations in a z-regular graph and an ER network with
, respectively. The recovery rate is set to
in both panels.
