A Tight Bound on Localization of Electrical Flows
Ori Gurel-Gurevich, Asaf Nachmias, Sushant Sachdeva
We prove that for any unweighted graph on n vertices the L1 norm of a unit electric current between the endpoints of a random edge is at most 2 log n. Furthermore, we show that on…
Long-term balanced allocation via thinning
Ohad N. Feldheim, Ori Gurel-Gurevich, Jiange Li
We study the long-term behavior of the two-thinning variant of the classical balls-and-bins model. In this model, an overseer is provided with uniform random allocation of ball…
Recurrence of a Weighted Random Walk on a Circle Packing with Parabolic Carrier
Ori Gurel-Gurevich, Matan Seidel
In this paper we show that given a circle packing of an infinite planar triangulation such that its carrier is parabolic, placing weights on the edges according to a certain natura…
A Note on Costs Minimization with Stochastic Target Constraints
Yan Dolinsky, Benjamin Gottesman, Ori Gurel-Gurevich
We study the minimization of the expected costs under stochastic constraint at the terminal time. The first and the main result says that for a power type of costs, the value funct…
The Dirichlet problem for orthodiagonal maps
Ori Gurel-Gurevich, Daniel C. Jerison, Asaf Nachmias
We prove that the discrete harmonic function corresponding to smooth Dirichlet boundary conditions on orthodiagonal maps, that is, plane graphs having quadrilateral faces with orth…
A combinatorial criterion for macroscopic circles in planar triangulations
Ori Gurel-Gurevich, Daniel C. Jerison, Asaf Nachmias
Given a finite simple triangulation, we estimate the sizes of circles in its circle packing in terms of Cannon's vertex extremal length. Our estimates provide control over the size…
