We study the existence and the regularity of the local time of filtered white noises . We will also give Chung’s form of the law of iterated logarithm for , this shows that the result on the Hölder regularity, with respect to time, of the local time is sharp.
Mots clés : Local time, Local nondeterminism, Chung’s type law of iterated logarithm, Filtered white noises.
