Small-time Chung Laws for L evy processes

Abstract

In this thesis we review and add to the literature extending the so-called `other' law of the iterated logarithm of Chung (1948). By adapting the large-time techniques of Rushton (2007) to the small-time setting and employing and slightly extending a characterisation result of Maller and Mason (2008), we derive both one-dimensional and functional Chung laws for a large class of Levy processes lying in the domain of attraction of strictly stable laws at zero. In particular, our results extend the work of Buchmann and Maller (2011) to encompass processes with vanishing Gaussian component lying in the domain of attraction of a normal distribution at zero.
