Gaugeability for Feynman-kac Functionals with Applications to Symmetric Α-stable Processes
نویسندگان
چکیده
For symmetric α-stable processes, an analytic criterion for a measure being gaugeable was obtained by Z.-Q. Chen (2002), M. Takeda (2002) and M. Takeda and T. Uemura (2004). Applying it, we consider the ultracontractivity of Feynman-Kac semigroups and expectations of the number of branches hitting closed sets in branching symmetric α-stable processes.

Feynman-kac Penalisations of Symmetric Stable Pro- Cesses
In [9], [10], B. Roynette, P. Vallois and M. Yor have studied limit theorems for Wiener processes normalized by some weight processes. In [16], K. Yano, Y. Yano and M. Yor studied the limit theorems for the one-dimensional symmetric stable process normalized by non-negative functions of the local times or by negative (killing) Feynman-Kac functionals. They call the limit theorems for Markov pro...
متن کاملJa n 20 04 Relative Fatou ’ s Theorem for ( − ∆ ) α / 2 - harmonic Functions in Bounded κ - fat Open Set ∗
Recently it was shown in Kim [26] that Fatou's theorem for transient censored α-stable processes in a bounded C 1,1 open set is true. Here we give a probabilistic proof of relative Fatou's theorem for (−∆) α/2-harmonic functions (equivalently for symmetric α-stable processes) in bounded κ-fat open set where α ∈ (0, 2). That is, if u is positive (−∆) α/2-harmonic function in a bounded κ-fat open...
متن کاملAnalytic Properties of Fractional Schrödinger Semigroups and Gibbs Measures for Symmetric Stable Processes
We establish a Feynman-Kac-type formula to define fractional Schrödinger operators for (fractional) Kato-class potentials as self-adjoint operators. In this functional integral representation symmetric α-stable processes appear instead of Brownian motion. We derive asymptotic decay estimates on the ground state for potentials growing at infinity. We prove intrinsic ultracontractivity of the Fey...
متن کاملFeynman-Kac formula for fractional heat equation driven by fractional white noise
In this paper we obtain a Feynman-Kac formula for the solution of a fractional stochastic heat equation driven by fractional noise. One of the main difficulties is to show the exponential integrability of some singular nonlinear functionals of symmetric stable Lévy motion. This difficulty will be overcome by a technique developed in the framework of large deviation. This Feynman-Kac formula is ...
متن کاملOn the Estimates of the Density of Feynman-Kac Semigroups of α-Stable-like Processes
Suppose that α ∈ (0, 2) and that X is an α-stable-like process on R d. Let F be a function on R d belonging to the class J d,α (see Introduction) and A F t be s≤t F (X s− , X s), t > 0, a discontinuous additive functional of X. With neither F nor X being symmetric, under certain conditions, we show that the Feynman-Kac semigroup {S F t : t ≥ 0} defined by S F t f (x) = E x (e −A F t f (X t)) ha...
