Abstract:
The transient behavior of an ecosystem with N random interacting
species in the presence of a multiplicative noise is analyzed. The
multiplicative noise mimics the interaction with the environment.
We investigate different asymptotic dynamical regimes and the role
of the external noise on the probability distribution of the local
field.
