About viability and minimal time crisis problem for the Lotka-Volterra prey-predator model
Résumé
We study the minimal time crisis problem for the classical Lotka-Volterra prey-predator model.
Our aim is to maintain the system in a subset K for which the number of preys is above a given threshold.
In the case where the viability kernel of K is non-empty, we provide an analytic description of this set and compute the minimal time function steering the system to this set. We compare this strategy with the minimal time crisis function that is computed numerically via a regularization method.
We also investigate the minimal time crisis problem numerically in the case where the viability kernel is empty.
