3.2.1 Kramers’ law

Given the results of Lemmas 3.2 and 3.5, we expect our process to spend most of its time near a with σ small enough. In order to have more information about this behaviour, we introduce the following stopping times

\

\

\

\ That gives us:

\

\

\ Therefore, by induction in k, we get:

\

\ By Markov’s inequality, we get:

\

\ We remark that by Lemmas 3.1, 3.5 and derivations above, we have

\

\ This concludes the proof.
