摘要
Recently, the author has proposed an elementary theory of conserved quantities and symmetry for stochastic dynamical systems described by stochastic differential equations of Stratonovich type. Within the framework, a new method for deriving conserved quantities from symmetry is developed ina similar manner to that of Hojman's work which gives a new conservation law constructed without using either Lagrangians or Hamiltonians for deterministic dynamical systems. Some examples of the conserved quantities obtained through the new method are given.
