Titolo: Random forests and Markovian spectra
Abstract:
Starting from a theorem of Michelli and Willoughby we will see how
some loop-erased random walk make a bridge between the spanning forest
of a graph and the spectrum of its Laplacian. We will give more
examples of the links between these two sets, introducing in
particular a fragmentation and coalescence process that allows for the
study of this spectrum from a probabilistic point of view.
