Consider a collection of random variables attached to the vertices of a graph. The reconstruction problem requires to estimate one of them given far away' observations. Several theoretical results (and simple algorithms) are available when (heir joint probal)ility distribution is Markov with respect to a tree. In this paper we consider the case of sequences(More)
We study by means of numerical simulations the velocity reversal model, a onedimensional mechanical model of heat transport introduced in 1985 by Ianiro and Lebowitz. Our numerical results indicate that this model, which does not conserve momentum, exhibits nevertheless an anomalous Fourier’s law similar to the ones previously observed in(More)
