Entropic CLT and phase transition in high-dimensional Wishart matrices
Sébastien Bubeck, Shirshendu Ganguly
We consider high dimensional Wishart matrices where the entries of are i.i.d. from a log-concave distribut…
Non-fixation for conservative stochastic dynamics on the line
Riddhipratim Basu, Shirshendu Ganguly, Christopher Hoffman
We consider Activated Random Walk (ARW), a model which generalizes the Stochastic Sandpile, one of the canonical examples of self organized criticality. Informally ARW is a particl…
Recovery and Rigidity in a Regular Stochastic Block Model
Gerandy Brito, Ioana Dumitriu, Shirshendu Ganguly +2
The stochastic block model is a natural model for studying community detection in random networks. Its clustering properties have been extensively studied in the statistics, physic…
Heat diffusion with frozen boundary
Laura Florescu, Shirshendu Ganguly, Yuval Peres +1
Consider "Frozen Random Walk" on : particles start at the origin. At any discrete time, the leftmost and rightmost particles are "froz…
Competitive Erosion is Conformally Invariant
Shirshendu Ganguly, Yuval Peres
We study a graph-theoretic model of interface dynamics called . Each vertex of the graph is occupied by a particle, which can be either red or blue. New red…
Convergence of discrete Green functions with Neumann boundary conditions
Shirshendu Ganguly, Yuval Peres
In this note we prove convergence of Green functions with Neumann boundary conditions for the random walk to their continuous counterparts. Also a few Beurling type hitting estimat…
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…
