Martingales and first passage times of AR(1) sequences
Alexander Novikov, Nino Kordzakhia
Using the martingale approach we find sufficient conditions for exponential boundedness of first passage times over a level for ergodic first order autoregressive sequences (AR(1))…

On exit times of Levy-driven Ornstein--Uhlenbeck processes
K. Borovkov, A. Novikov
We prove two martingale identities which involve exit times of Levy-driven Ornstein--Uhlenbeck processes. Using these identities we find an explicit formula for the Laplace transfo…
