Poissonian potential measures for refracted-reflected Lévy processes
Noah Beelders, Lewis Ramsden, Apostolos D. Papaioannou
In this paper we study the potential measures and the Laplace transforms of the occupation times of a refracted-reflected spectrally negative Lévy process when the process is obser…
Lévy processes with partially stochastic resetting
Zbigniew Palmowski, Noah Beelders, Lewis Ramsden +1
In this paper, we solve exit problems for a Lévy process that resets proportionally to its current position at independent Poisson epochs times. This resetting causes an additional…
Lévy processes under level-dependent Poissonian switching
Noah Beelders, Lewis Ramsden, Apostolos D. Papaioannou
In this paper, we derive identities for the upward and downward exit problems and resolvents for a process whose motion changes between two Lévy processes if it is above (or below)…
Probabilistic Cauchy Functional Equations
Ehsan Azmoodeh, Noah Beelders, Yuliya Mishura
In this short note, we introduce probabilistic Cauchy functional equations, specifically, functional equations of the following form: $$ f(X_1 + X_2) \stackrel{d}{=} f(X_1) + f(X_2…
