Essay

We find neccessary and sufficient condition for renormalized local time existence for centered Gaussian random field in some Sobolev space. We determine all parameter values, that allow existence of renormalized self-intersection local time for fractional Brownian motion. We find simple sufficient condition for the existence of local time for Gaussian random field in the sense of convergence in probability.
