Intersection local times for interlacements
We define renormalized intersection local times for random interlacements of
L\'evy processes in R^{d} and prove an isomorphism theorem relating
renormalized intersection local times with associated Wick polynomials.Comment: SPA, to appea
Continuous Differentiability of Renormalized Intersection Local Times in R^{1}
We study , the k-fold renormalized
self-intersection local time for Brownian motion in . Our main result says
that is continuously differentiable in the spatial
variables, with probability 1
A sufficient condition for the continuity of permanental processes with applications to local times of Markov processes
We provide a sufficient condition for the continuity of real valued
permanental processes. When applied to the subclass of permanental processes
which consists of squares of Gaussian processes, we obtain the sufficient
condition for continuity which is also known to be necessary. Using an
isomorphism theorem of Eisenbaum and Kaspi which relates Markov local times and
permanental processes, we obtain a general sufficient condition for the joint
continuity of local times.Comment: Published in at http://dx.doi.org/10.1214/12-AOP744 the Annals of
