A note on a.s. finiteness of perpetual integral functionals of diffusions

چکیده
In this note we use the boundary classification of diffusions in order to derive a criterion for the convergence of perpetual integral functionals of transient real-valued diffusions. We present a second approach, based on Khas’minskii’s lemma, which is applicable also to spectrally negative Lévy processes. In the particular case of transient Bessel processes, our criterion agrees with the one obtained via Jeulin’s convergence lemma.

Perpetual Integrals for Lévy Processes
Given a Lévy process ξ , we find necessary and sufficient conditions for almost sure finiteness of the perpetual integral ∫ ∞ 0 f (ξs)ds, where f is a positive locally integrable function. If μ = E[ξ1] ∈ (0,∞) and ξ has local times we prove the 0–1 law P ( ∫ ∞ 0 f (ξs) ds < ∞ ) ∈ {0, 1} with the exact characterization P ( ∫ ∞ 0 f (ξs) ds < ∞ ) = 0 ⇐⇒ ∫ ∞ f (x) dx = ∞. The proof uses spatially s...
متن کاملGENERALIZED POSITIVE DEFINITE FUNCTIONS AND COMPLETELY MONOTONE FUNCTIONS ON FOUNDATION SEMIGROUPS
A general notion of completely monotone functionals on an ordered Banach algebra B into a proper H*-algebra A with an integral representation for such functionals is given. As an application of this result we have obtained a characterization for the generalized completely continuous monotone functions on weighted foundation semigroups. A generalized version of Bochner’s theorem on foundation se...

Optimal stopping of integral functionals and a “no-loss” free boundary formulation
This paper is concerned with a modification of the classical formulation of the free boundary problem for the optimal stopping of integral functionals in nonregular one-dimensional diffusions. This modification was introduced in a recent paper of Rüschendorf and Urusov (2007). As main result of that paper a verification theorem was established. Solutions of the modified free boundary problem im...
متن کاملOn a class of optimal stopping problems for diffusions with discontinuous coefficients
In this paper we introduce a modification of the free boundary problem related to optimal stopping problems for diffusion processes. This modification allows to apply this PDE method also in cases where the usual regularity assumptions on the coefficients and on the gain function are not satisfied. We apply this method to the optimal stopping of integral functionals with exponential discount of...
