Stochastic differential equations driven by Lévy noise are not so tidy as Itô diffusions driven by Brownian noise, so they are frequently brushed aside in stochastic calculus texts. But I need ’em! There is a developed sampling theory for these creatures called sparse stochastic process theory.

Schoutens, Leuven, and Studer (2001) give a tractable example for Poisson processes.

Possibly also chaos expansions might be a useful tool, and/or Malliavin calculus, whatever *that* is.

But I will express no opinions, because this is a placeholder for a topic on which I do not know enough yet. 🏗
