Potential spaces on fractals

Jiaxin Hu, Martina Zähle (2005)

Studia Mathematica

We introduce potential spaces on fractal metric spaces, investigate their embedding theorems, and derive various Besov spaces. Our starting point is that there exists a local, stochastically complete heat kernel satisfying a two-sided estimate on the fractal considered.

Processus de naissance avec interaction des voisins, évolution de graphes

Jacques Peyrière (1981)

Annales de l'institut Fourier

On définit de nouveaux processus de naissance à temps discret; la population est, à chaque instant, organisée en graphe. Pour obtenir la ( n + 1 ) -ième génération on remplace aléatoirement les sommets de la n -ième génération par des graphes que l’on accroche convenablement les uns aux autres. On autorise une certaine dépendance entre les substitutions de sommets voisins. On étudie, pour certains processus surcritiques, la croissance de la population et la structure des graphes générés : sous des hypothèses...

We review recent results on interface states in quantum statistical mechanics.

Quasi-polynomial mixing of the 2D stochastic Ising model with “plus” boundary up to criticality

Eyal Lubetzky, Fabio Martinelli, Allan Sly, Fabio Lucio Toninelli (2013)

Journal of the European Mathematical Society

We considerably improve upon the recent result of [37] on the mixing time of Glauber dynamics for the 2D Ising model in a box of side L at low temperature and with random boundary conditions whose distribution P stochastically dominates the extremal plus phase. An important special case is when P is concentrated on the homogeneous all-plus configuration, where the mixing time T M I X is conjectured to be polynomial in L . In [37] it was shown that for a large enough inverse-temperature β and any ϵ > 0 there...

Quenched non-equilibrium central limit theorem for a tagged particle in the exclusion process with bond disorder

M. D. Jara, C. Landim (2008)

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

For a sequence of i.i.d. random variables {ξx: x∈ℤ} bounded above and below by strictly positive finite constants, consider the nearest-neighbor one-dimensional simple exclusion process in which a particle at x (resp. x+1) jumps to x+1 (resp. x) at rate ξx. We examine a quenched non-equilibrium central limit theorem for the position of a tagged particle in the exclusion process with bond disorder {ξx: x∈ℤ}. We prove that the position of the tagged particle converges under diffusive scaling to a...
