A non-linear Riesz respresentation in probabilistic potential theory [PDF]

open access: closedAnnales de l'Institut Henri Poincare (B) Probability and Statistics, 2005
Let \((X_t)_{t\geq 0}\) be a Hunt process on a locally compact metric space \(S\). Define the nonlinear potential operator \(\overline{G}\) by \(\overline{G}f(x)=E_x\left(\int_0^\zeta \sup_{0\leq s\leq t} f(X_s) dt\right)\). The main purpose of this paper is to show the Riesz decomposition theorem relative to this potential, that is, for a given ...

Probabilistic potential theory and induction of dynamical systems [PDF]

open access: greenAnnales de l'Institut Henri Poincaré, Probabilités et Statistiques, 2021
In this article, we outline a version of a balayage formula in probabilistic potential theory adapted to measure-preserving dynamical systems. This balayage identity generalizes the property that induced maps preserve the restriction of the original invariant measure. As an application, we prove in some cases the invariance under induction of the Green-

Solving Semilinear Partial Differential Equations With Probabilistic Potential Theory [PDF]

open access: bronzeTransactions of the American Mathematical Society, 1985
Techniques of probabilistic potential theory are applied to solve − L u + f ( u ) = μ - Lu + f(u) = \mu , where μ \mu is a signed measure, f f a (possibly discontinuous) function and L L a second order elliptic or ...

How to clean a dirty floor: Probabilistic potential theory and the Dobrushin uniqueness theorem [PDF]

open access: greenMarkov Processes and Related Fields, 2007
Motivated by the Dobrushin uniqueness theorem in statistical mechanics, we consider the following situation: Let be a nonnegative matrix over a finite or countably infinite index set X, and define the "cleaning operators" _h = I_{1-h} + I_h for h: X \to [0,1] (here I_f denotes the diagonal matrix with entries f).

PROBABILISTIC APPROACH IN POTENTIAL THEORY TO THE EQUILIBRIUM PROBLEM [PDF]

open access: closedAnnales de l'Institut Fourier, 2008
A complete form of the classical theorem by Gauss-M. Riesz-Frostman is given for a large of Markov processes without the usual hypothesis of duality. The idea leads to a probabilistic solution of Robin’s problem and it is based on the last exit time from a transient set.

How to make unforgeable money in generalised probabilistic theories [PDF]

open access: yesQuantum, 2018
We discuss the possibility of creating money that is physically impossible to counterfeit. Of course, "physically impossible" is dependent on the theory that is a faithful description of nature.

On the existence of positive solutions of nonlinear elliptic equations—a probabilistic potential theory approach

open access: closedDuke Mathematical Journal, 1993
We study the existence of solutions to the problem \[ \begin{cases} \Delta u+K(x) f(u)=0 \quad & \text{ in } D \\ u>0 & \text{ in } D \\ u=0 & \text{ on } \partial D. \end{cases} \tag{I} \] Our goal is to prove an existence theorem for problem (I) in a general setting by using Brownian path integration method and the potential theory.
