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 $Z$ . 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 $Z^{d}$ , for $d \geq 2$ , for any jumping parameters $p_1, p_2 \i…

Branching random walk in the presence of a hard wall

Rishideep Roy

We consider a branching random walk on a $d$ -ary tree of height $n$ ( $n \in N$ ), under the presence of a hard wall which restricts each value to be positive, where $d$ is…

Convergence of the centered maximum of log-correlated Gaussian fields

Jian Ding, Rishideep Roy, Ofer Zeitouni

We show that the centered maximum of a sequence of log-correlated Gaussian fields in any dimension converges in distribution, under the assumption that the covariances of the field…
