Uniqueness of the stationary distribution and stabilizability in Zhang's sandpile model
Anne Fey, Haiyan Liu, Ronald Meester
We show that Zhang's sandpile model (N,[a,b]) on N sites and with uniform additions on [a,b] has a unique stationary measure for all 0 <= a < b <= 1. This generalizes earlier resul…
Large deviations for eigenvalues of sample covariance matrices, with applications to mobile communication systems
Anne Fey, Remco van der Hofstad, Marten Klok
We study sample covariance matrices of the form , where is a matrix with i.i.d. mean zero entries. This is a generalization of so-called Wishart m…
Stabilizability and percolation in the infinite volume sandpile model
Anne Fey, Ronald Meester, Frank Redig
We study the sandpile model in infinite volume on . In particular, we are interested in the question whether or not initial configurations, chosen according to a stat…
Organized versus self-organized criticality in the abelian sandpile model
A. Fey, F. Redig
We define stabilizability of an infinite volume height configuration and of a probability measure on height configurations. We show that for high enough densities, a probability me…
