How fast do rumours spread?
Rishideep Roy, Kumarjit Saha
We study a rumour propagation model along the lines of \cite{lebensztayn2008disk} as a long-range percolation model on . We begin by showing a sharp phase transition-type behav…
Coexistence in discrete time Multi-type competing Frog Models
Rishideep Roy, Kumarjit Saha
We study coexistence in discrete time multi-type frog models. We first show that for two types of particles on , for , for any jumping parameters $p_1, p_2 \i…
Transmission and navigation on disordered lattice networks, directed spanning forests and Brownian web
Subhroshekhar Ghosh, Kumarjit Saha
Stochastic networks based on random point sets as nodes have attracted considerable interest in many applications, particularly in communication networks, including wireless sensor…
The 2d-directed spanning forest converges to the Brownian web
David Coupier, Kumarjit Saha, Anish Sarkar +1
The two-dimensional directed spanning forest (DSF) introduced by Baccelli and Bordenave is a planar directed forest whose vertex set is given by a homogeneous Poisson point process…
Collision times of random walks and applications to the Brownian web
David Coupier, Kumarjit Saha, Anish Sarkar +1
Convergence of directed forests, spanning on random subsets of lattices or on point processes, towards the Brownian web has made the subject of an abundant literature, a large part…
