Itô calculus and jump diffusions for $G$-Lévy processes

The paper considers the integration theory for $G$-Lévy processes with finite activity. We introduce the Itô-Lévy integrals, give the Itô formula for them and establish SDE's, BSDE's and decoupled FBSDE's driven by $G$-Lévy processes. In order to develop such a theory, we prove two key results: the representation of the sublinear expectation associated with a $G$-Lévy process and a characterization of random variables in $L^p_G(Ω)$ in terms of their quasi-continuity.
