Concentration of the Brownian bridge on Cartan-Hadamard manifolds with pinched negative sectional curvature

Marc Arnaudon, Thomas Simon (2005)

Annales de l’institut Fourier

Similarity:

We study the rate of concentration of a Brownian bridge in time one around the corresponding geodesical segment on a Cartan-Hadamard manifold with pinched negative sectional curvature, when the distance between the two extremities tends to infinity. This improves on previous results by A. Eberle, and one of us . Along the way, we derive a new asymptotic estimate for the logarithmic derivative of the heat kernel on such manifolds, in bounded time and with one...

Brownian penalisations related to excursion lengths, VII

B. Roynette, P. Vallois, M. Yor (2009)

Annales de l'I.H.P. Probabilités et statistiques

Similarity:

Limiting laws, as →∞, for brownian motion penalised by the longest length of excursions up to , or up to the last zero before , or again, up to the first zero after , are shown to exist, and are characterized.
