AbstractWe apply a proposal of Yuen and Tombesi, for treating stochasticproblems with negative diffusion, to the analytically solubleproblem of the single-mode anharmonic oscillator. We find thatthe associated stochastic realizations include divergenttrajectories. It is possible, however, to solve the stochasticproblem exactly, but the averaging must be performed withgreat care.
