Some Connections Between (Sub)Critical Branching Mechanisms and Bernstein Functions

Jean Bertoin, Bernard Roynette, Marc Yor

We describe some connections, via composition, between two functional spaces: the space of (sub)critical branching mechanisms and the space of Bernstein functions. The functions ${…

On local martingale and its supremum: harmonic functions and beyond

Jan Obloj, Marc Yor

We discuss certain facts involving a continuous local martingale and its supremum . A complete characterization of -harmonic functions is proposed. This y…

Harnesses, Levy bridges and Monsieur Jourdain

Roger Mansuy, Marc Yor

Relations between so-called harness processes and initial enlargements of the filtration of a Levy process with its positions at fixed times are investigated.

A definition and some characteristic properties of pseudo-stopping times

Ashkan Nikeghbali, Marc Yor

Recently, D. Williams \cite{williams} gave an explicit example of a random time associated with Brownian motion such that is not a stopping time but $\mathbb{E}M_ρ=\mathbb{…

Asymptotic laws for regenerative compositions: gamma subordinators and the like

A. Gnedin, J. Pitman, M. Yor

For a random closed set obtained by exponential transformation of the closed range of a subordinator, a regenerative composit…

Where did the Brownian particle go?

Robin Pemantle, Yuval Peres, Jim Pitman +1

Consider the radial projection onto the unit sphere of the path a d-dimensional Brownian motion W, started at the center of the sphere and run for unit time. Given the occupation m…
