Unique continuation on planar graphs
Ahmed Bou-Rabee, William Cooperman, Shirshendu Ganguly
We show that a discrete harmonic function which is bounded on a large portion of a periodic planar graph is constant. A key ingredient is a new unique continuation result for the w…
Formation of an interface by competitive erosion
Shirshendu Ganguly, Lionel Levine, Yuval Peres +1
In 2006, the fourth author proposed a graph-theoretic model of interface dynamics called competitive erosion. Each vertex of the graph is occupied by a particle that can be either…
The Random Transposition Dynamics on Random Regular Graphs and the Gaussian Free Field
Shirshendu Ganguly, Soumik Pal
A single permutation, seen as union of disjoint cycles, represents a regular graph of degree two. Consider many independent random permutations and superimpose their graph stru…
Oil and water: a two-type internal aggregation model
Elisabetta Candellero, Shirshendu Ganguly, Christopher Hoffman +1
We introduce a two-type internal DLA model which is an example of a non-unary abelian network. Starting with n "oil" and n "water" particles at the origin, the particles diffuse in…
Permuted Random Walk Exits Typically in Linear Time
Shirshendu Ganguly, Yuval Peres
Given a permutation sigma of the integers {-n,-n+1,...,n} we consider the Markov chain X_{sigma}, which jumps from k to sigma (k\pm 1) equally likely if k\neq -n,n. We prove that t…
