Large Deviations for One Dimensional Diffusions with a Strong Drift
2008-09-01
I present a large deviation principle that describes how one-dimensional diffusion processes behave under the influence of a strong drift, combining classical results with a new term that accounts for the cost of Brownian motion staying near equilibrium points. This theoretical work extends the Freidlin-Wentzell theorem to the regime of increasingly strong drifts.
