Uncertain dynamical systems defined by pseudomeasures
- Fachbereich Physik, Universitaet GH Essen, 45117 Essen (Germany)
This paper deals with uncertain dynamical systems in which predictions about the future state of a system are assessed by so-called pseudomeasures. Two special cases are stochastic dynamical systems, where the pseudomeasure is the conventional probability measure, and fuzzy dynamical systems in which the pseudomeasure is a so-called possibility measure. New results about possibilistic systems and their relation to deterministic and to stochastic systems are derived by using idempotent pseudolinear algebra. By expressing large deviation estimates for stochastic perturbations in terms of possibility measures, we obtain a new interpretation of the Freidlin{endash}Wentzell quasipotentials for stochastic perturbations of dynamical systems as invariant possibility densities. {copyright} {ital 1997 American Institute of Physics.}
