Keywords Limit theorems for stochastic processes, ergodic theory for random dynamical systems

My research interest is to investigate limit properties for stochastic processes. I have studied generalizastions of Lévy's arcsine law for the one-dimensional random walk to general one-dimensional diffusions and to random dynamical systems with indifferent-in-average fixed points. I have also studied various limit theorems for Lévy processes which are related to the penalisation problem, i.e., the problem of conditional long-time limit preventing from certain behaviours.
