Heat kernel and Green function estimates on affine buildings of type
Jean-Philippe Anker, Bruno Schapira, Bartosz Trojan
We obtain a global estimate of the transition density associated to a nearest neighbor random walk, called here "simple", on affine buildings of type .…
Distributions that are convolvable with generalized Poisson kernel of solvable extensions of homogeneous Lie groups
Ewa Damek, Jacek Dziubanski, Philippe Jaming +1
In this paper, we characterize the class of distributions on an homogeneous Lie group $\fN$ that can be extended via Poisson integration to a solvable one-dimensional extension $\f…
Sinai's walk: a statistical aspect
Pierre Andreoletti
We consider Sinai's random walk in random environment. We prove that the logarithm of the local time is a good estimator of the random potential associated to the random environmen…
Metastability in Interacting Nonlinear Stochastic Differential Equations II: Large-N Behaviour
Nils Berglund, Bastien Fernandez, Barbara Gentz
We consider the dynamics of a periodic chain of N coupled overdamped particles under the influence of noise, in the limit of large N. Each particle is subjected to a bistable local…
Metastability in Interacting Nonlinear Stochastic Differential Equations I: From Weak Coupling to Synchronisation
Nils Berglund, Bastien Fernandez, Barbara Gentz
We consider the dynamics of a periodic chain of N coupled overdamped particles under the influence of noise. Each particle is subjected to a bistable local potential, to a linear c…
On the stabilization problem for nonholonomic distributions
Ludovic Rifford, Emmanuel Trélat
Let be a smooth connected and complete manifold of dimension , and be a smooth nonholonomic distribution of rank on . We prove that, if there exists a smoot…
