Modelling Illiquid Stocks Using Quantum Stochastic Calculus: Asymptotic Methods (2302.05256v1)
Published 10 Feb 2023 in q-fin.MF
Abstract: 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.
