Starting from the logistic equation we introduce
uncertainty on the parameters and then we look for stochastic stationary
solutions and conditions for their stability. In the stochastic case
we do not obtain all the deterministic stationary solutions, but we can
find invariant distributions which can be considered the stochastic analogue
of the deterministic stationary solutions. In particular, in this work
we give conditions on the parameters of the equation under which these
invariant distributions exist and conditions under which the stationary
solutions are stable.
