S. Albeverio et Sm. Fei, A REMARK ON SYMMETRY OF STOCHASTIC DYNAMICAL-SYSTEMS AND THEIR CONSERVED QUANTITIES, Journal of physics. A, mathematical and general, 28(22), 1995, pp. 6363-6371
The symmetry properties of stochastic dynamical systems described by a
stochastic differential equation of Stratonovich type and related con
served quantities are discussed, extending previous results by Misawa.
New conserved quantities are given by applying symmetry operators to
known conserved quantities. Some detailed examples are presented.
