A negative answer to Nevanlinna's type question and a parabolic surface with a lot of negative curvature
Itai Benjamini, Sergei Merenkov, Oded Schramm
Consider a simply connected Riemann surface represented by a Speiser graph. Nevanlinna asked if the type of the surface is determined by the mean excess of the graph: whether mean…
Mixing times of the biased card shuffling and the asymmetric exclusion process
Itai Benjamini, Noam Berger, Christopher Hoffman +1
Consider the following method of card shuffling. Start with a deck of cards numbered 1 through N. Fix a parameter between 0 and 1. In this model a ``shuffle'' consists of u…
Percolation on finite graphs and isoperimetric inequalities
Noga Alon, Itai Benjamini, Alan Stacey
Consider a uniform expanders family G_n with a uniform bound on the degrees. It is shown that for any p and c>0, a random subgraph of G_n obtained by retaining each edge, randomly…
Transience of percolation clusters on wedges
Omer Angel, Itai Benjamini, Noam Berger +1
We study random walks on supercritical percolation clusters on wedges in , and show that the infinite percolation cluster is (a.s.) transient whenever the wedge is transient.…
Determining the Genus of a Map by Local Observation of a Simple Random Process
Itai Benjamini, Laszlo Lovasz
Given a graph embedded in an orientable surface, a process consisting of random excitations and random node and face balancing is constructed and analyzed. It is shown that given a…
