[图书][B] Random walks on disordered media and their scaling limits

T Kumagai - 2014 - Springer
The main theme of these lecture notes is to analyze heat conduction on disordered media
such as fractals and percolation clusters by means of both probabilistic and analytic …

[图书][B] Resistance forms, quasisymmetric maps and heat kernel estimates

J Kigami - 2012 - ams.org
Assume that there is some analytic structure, a differential equation or a stochastic process
for example, on a metric space. To describe asymptotic behaviors of analytic objects, the …

Subsequential scaling limits of simple random walk on the two-dimensional uniform spanning tree

MT Barlow, DA Croydon, T Kumagai - 2017 - projecteuclid.org
The first main result of this paper is that the law of the (rescaled) two-dimensional uniform
spanning tree is tight in a space whose elements are measured, rooted real trees …

Scaling limits of the three-dimensional uniform spanning tree and associated random walk

O Angel, DA Croydon, S Hernandez-Torres… - The Annals of …, 2021 - projecteuclid.org
We show that the law of the three-dimensional uniform spanning tree (UST) is tight under
rescaling in a space whose elements are measured, rooted real trees, continuously …

[HTML][HTML] Heat kernel fluctuations and quantitative homogenization for the one-dimensional Bouchaud trap model

S Andres, DA Croydon, T Kumagai - Stochastic Processes and their …, 2024 - Elsevier
We present on-diagonal heat kernel estimates and quantitative homogenization statements
for the one-dimensional Bouchaud trap model. The heat kernel estimates are obtained using …

Diffusion on the scaling limit of the critical percolation cluster in the diamond hierarchical lattice

BM Hambly, T Kumagai - Communications in Mathematical Physics, 2010 - Springer
We construct critical percolation clusters on the diamond hierarchical lattice and show that
the scaling limit is a graph directed random recursive fractal. A Dirichlet form can be …

Random walks on decorated Galton-Watson trees

E Archer - arXiv preprint arXiv:2011.07266, 2020 - arxiv.org
In this article, we study a simple random walk on a decorated Galton-Watson tree, obtained
from a Galton-Watson tree by replacing each vertex of degree $ n $ with an independent …

Heat kernel fluctuations for stochastic processes on fractals and random media

S Andres, D Croydon, T Kumagai - From Classical Analysis to Analysis on …, 2023 - Springer
It is well known that stochastic processes on fractal spaces or in certain random media
exhibit anomalous heat kernel behaviour. One manifestation of such irregular behaviour is …

Scaling limits for simple random walks on random ordered graph trees

DA Croydon - Advances in Applied Probability, 2010 - cambridge.org
Consider a family of random ordered graph trees (Tn) n≥ 1, where Tn has n vertices. It has
previously been established that if the associated search-depth processes converge to the …

Scaling limit for the random walk on the largest connected component of the critical random graph

A scaling limit for the simple random walk on the largest connected component of the Erdos–
Rényi random graph G (n, p) in the critical window, p= n− 1+ λn− 4/3, is deduced. The …
