Subject:
Necessary conditions were found for the existence of local times of sample paths of Gaussian processes. A class of stationary processes which do not have local time was discovered. A fiber method was developed for study of distributions of stochastic functionals. of the processes with independent increments. Necessary and sufficient conditions for validity of the functional law of iterated logarithm for Wiener process with respect to arbitrary norm were found.New almost sure limit theorems were found for sums of independent variables and for martingales. The small ball probabilities were investigated for Wiener process with respect to weighted norms as well as their applications to analytic properties of Volterra operators.
