  This article investigates the Fokker-Planck equations that arise from the
application of quantum stochastic calculus to the modelling of illiquid
financial markets, using asymptotic methods. We present a power series solution
for quantum stochastic processes with a non-zero conservation process. Whilst
the series in question are in general divergent, we show they can be used to
approximate solutions for longer time frames, and provide estimates for the
relative error on the higher order terms.
