    Smooth random functions, random ODEs, and Gaussian processes by Filip, S, Javeed, A, Trefethen, L

    Published 2019
    “…For example, one can solve smooth random ordinary differential equations using standard mathematical definitions and numerical algorithms, rather than having to develop new definitions and algorithms of stochastic differential equations. In the limit as the number of Fourier coefficients defining a smooth random function goes to $\infty$, one obtains the usual stochastic objects in what is known as their Stratonovich interpretation.…”
