    "abstract": "We apply a proposal of Yuen and Tombesi, for treating stochastic problems\nwith negative diffusion, to the analytically soluble problem of the single-mode\nanharmonic oscillator. We find that the associated stochastic realizations\ninclude divergent trajectories. It is possible, however, to solve the\nstochastic problem exactly, but the averaging must be performed with great\ncare.",
