Abstract
Supertrack orbits are used to investigate boundary crises in an one-dimensional, two-parameter (\(\nu ,\beta \)), nonlinear Gauss map. After the crises, the time evolution of the orbit is shown to be pseudo-chaotic. We investigate the chaotic transient, that is, the time an orbit spends in a region where the chaotic attractor existed prior to the crisis, and confirm it decays exponentially with time. The relaxation time is given by a power-law \(\tau \propto \mu ^{\gamma }\) with \(\mu =|\beta -\beta _c|\) corresponding to the distance measured in the parameter where the crises are observed. \(\beta _c\) is the parameter that characterizes the occurrence of a boundary crisis and the numerical value of the power measured was \(\gamma =1/2\).
