A Sharp Phase Transition for Killed Branching Random Walks with Heavy-Tailed Displacements
Ramkrishna Jyoti Samanta
We study the survival of a branching random walk in a supercritical Galton-Watson tree subject to a deterministic, superlinear killing barrier with heavy-tailed displacements. For…
Long-term behaviour of refracted Lévy processes in a half-line
Ramkrishna Jyoti Samanta, Alexander R. Watson
We study the long-term behaviour of refracted Lévy processes within a half-line, with killing on exiting the domain and at state-dependent rate inside it. We identify the decay rat…
Mixing Phases and Metastability for the Glauber Dynamics on the p-Spin Curie-Weiss Model
Ramkrishna Jyoti Samanta, Somabha Mukherjee, Jiang Zhang
The Glauber dynamics for the classical -spin Curie-Weiss model on nodes with inverse temperature and zero external field is known to mix in time for $β< \fr…
Detecting Change-points in Mean of Multivariate Time Series
Ramkrishna Jyoti Samanta
This work delves into presenting a probabilistic method for analyzing linear process data with weakly dependent innovations, focusing on detecting change-points in the mean and est…
Orderings of extremes among dependent extended Weibull random variables
Ramkrishna Jyoti Samanta, Sangita Das, N. Balakrishnan
In this work, we consider two sets of dependent variables and , where and $Y_{i}\sim EW(β_{i},μ_{…
Optimizing the location of the colony of foragers with Collective Learning
Sanchayan Bhowal, Ramkrishna Jyoti Samanta, Arnob Ray +2
Animal groups collaborate with one another throughout their lives to better comprehend their surroundings. Here, we try to model, using continuous random walks, how the entire proc…
