Additive Functionals of Several Lévy Processes and Intersection Local Times

Different extensions of an isomorphism theorem of Dynkin are developed and are used to study two distinct but related families of functionals of Lévy processes; n-fold “near-intersections” of a single Lévy process and continuous additive functionals of several independent Lévy processes. Intersection local times for n independent Lévy processes are also studied. They are related to both of the ...

Additive functionals of several Lévy processes and self-intersection local times

Different extentons of an isomorphism theorem of Dynkin are developed and are used to study two distinct but related families of functionals of Lévy processes; n-fold “near-intersections” of a single Lévy process, which is also referred to as a self-intersection local time, and continuous additive functionals of several independent Lévy processes. Intersection local times for n independent Lévy...

Local Times of Additive Lévy Processes

Let X = {X(t); t ∈ R+} be an additive Lévy process in R with X(t) = X1(t1) + · · ·+ XN (tN ), ∀t ∈ R+ , where X1, · · · , XN are independent, classical Lévy processes on R with Lévy exponents Ψ1, . . . , ΨN respectively. Under mild regularity conditions on the Ψi’s, we derive moment estimates that imply joint continuity of the local times in question. These results are then refined to precise e...

Renormalized self-intersection local times and Wick power chaos processes

Sufficient conditions are obtained for the continuity of renormalized self-intersection local times for the multiple intersections of a large class of strongly symmetric Lévy processes in Rm, m = 1, 2. In R2 these include Brownian motion and stable processes of index greater than 3/2, as well as many processes in their domains of attraction. In R1 these include stable processes of index 3/4 < β...

Additive functionals and excursions of Kuznetsov processes

Let B be a continuous additive functional for a standard process (Xt)t∈R+ and let (Yt)t∈R be a stationary Kuznetsov process with the same semigroup of transition. In this paper, we give the excursion laws of (Xt)t∈R+ conditioned on the strict past and future without duality hypothesis. We study excursions of a general regenerative system and of a regenerative system consisting of the closure of...
