Fast/slow Diffusion and Collapsing Sandpiles
We regard the limit as p ! 1 of the ow governed by the p-Laplacian as providing a simplistic model for the \collapse of an initially unstable sandpile." Upon rescaling to stretch out the initial layer we obtain some simple dynamics and provide fairly explicit solutions in certain cases. In particular we note that such models entail \instanta-neous" mass transfer governed by Monge-Kantorovich th...
متن کاملComparing fixed and collapsing boundary versions of the diffusion model.
Optimality studies and studies of decision-making in monkeys have been used to support a model in which the decision boundaries used to evaluate evidence collapse over time. This article investigates whether a diffusion model with collapsing boundaries provides a better account of human data than a model with fixed boundaries. We compared the models using data from four new numerosity discrimin...
متن کاملLadder Sandpiles
We study Abelian sandpiles on graphs of the form G×I, where G is an arbitrary finite connected graph, and I ⊂ Z is a finite interval. We show that for any fixed G with at least two vertices, the stationary measures μI = μG×I have two extremal weak limit points as I ↑ Z. The extremal limits are the only ergodic measures of maximum entropy on the set of infinite recurrent configurations. We show ...
متن کاملSandpiles and Dominos
We consider the subgroup of the abelian sandpile group of the grid graph consisting of configurations of sand that are symmetric with respect to central vertical and horizontal axes. We show that the size of this group is (i) the number of domino tilings of a corresponding weighted rectangular checkerboard; (ii) a product of special values of Chebyshev polynomials; and (iii) a double-product wh...
متن کاملAsymmetric Abelian Avalanches and Sandpiles
We consider two classes of threshold failure models, Abelian avalanches and sandpiles, with the redistribution matrices satisfying natural conditions guaranteeing absence of infinite avalanches. We investigate combinatorial structure of the set of recurrent configurations for these models and the corresponding statistical properties of the distribution of avalanches. We introduce reduction oper...
