Spectrum Estimation through Kirchhoff Random Forests
Simon Barthelmé, Fabienne Castell, Alexandre Gaudillière +3
Given a non-oriented edge-weighted graph, we show how to make some estimation of the associated Laplacian eigenvalues through Monte Carlo evaluation of spectral quantities computed…
Random Forests and Networks Analysis
L. Avena, F. Castell, A. Gaudilliere +1
D. Wilson~\cite{[Wi]} in the 1990's described a simple and efficient algorithm based on loop-erased random walks to sample uniform spanning trees and more generally weighted trees…
Approximate and exact solutions of intertwining equations through random spanning forests
Luca Avena, Fabienne Castell, Alexandre Gaudillière +1
For different reversible Markov kernels on finite state spaces, we look for families of probability measures for which the time evolution almost remains in their convex hull. Motiv…
Exponential moments of self-intersection local times of stable random walks in subcritical dimensions
Fabienne Castell, Clément Laurent, Clothilde Mélot
Let be an -stable random walk with values in . Let be its local time. For , not necessarily integer, $I_t = \sum_x l…
