The Kramers problem for SDEs driven by small, accelerated L\'evy noise with exponentially light jumps

We establish Freidlin-Wentzell results for a nonlinear ordinary differential equation starting close to the stable state $0$, say, subject to a perturbation by a stochastic integral which is driven by an $\epsilon$-small and $(1\mathrm{/}\epsilon )$-accelerated L'evy process with exponentially light jumps. For this purpose we derive a large deviations principle for the stochastically perturbed system using the weak convergence approach developed by Budhiraja, Dupuis, Maroulas and collaborators in recent years. In the sequel we solve the associated asymptotic first escape problem from the bounded neighborhood of $0$ in the limit as $\epsilon \to 0$ which is also known as the Kramers problem in the literature.
