Abstract: | Summary LetL(x, T),xRd,TR+N, be the local time of theN-parameter Wiener processW taking values inRd. Even in the distribution valued casedd2N,L can be described in a series representation by means of multiple Wiener-Ito integrals. This setting proves to be a good starting point for the investigation of the asymptotic behaviour ofL(x, T) as |x|0 and/orT and of related occupation integrals asT. We obtain the rates of explosion in laws of the first order, i.e. normalized convergence laws forL(x, T) resp.XT(f), and of the second order, i.e. normalized convergence laws forL(x, T)–E(L(x, T)) resp.XT(f)–E(XT(f)).This research was made during a stay at the LMU in München supported by DAAD |
