Extremes of Multi-type Branching Random Walks: Heaviest Tail Wins
Ayan Bhattacharya, Krishanu Maulik, Zbigniew Palmowski +1
We consider a branching random walk on a multi()-type, supercritical Galton-Watson tree which satisfies Kesten-Stigum condition. We assume that the displacements associated with…
A large sample test for the length of memory of stationary symmetric stable random fields via nonsingular -actions
Ayan Bhattacharya, Parthanil Roy
Based on the ratio of two block maxima, we propose a large sample test for the length of memory of a stationary symmetric -stable discrete parameter random field. We show that t…
Branching Random Walks, Stable Point Processes and Regular Variation
Ayan Bhattacharya, Rajat Subhra Hazra, Parthanil Roy
Using the language of regular variation, we give a sufficient condition for a point process to be in the superposition domain of attraction of a strictly stable point process. This…
