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( $Q$ )-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 $Z^{d}$ -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 $α$ -stable discrete parameter random field. We show that t…

Fluctuations of eigenvalues of patterned random matrices

Kartick Adhikari, Koushik Saha

In this article we study the fluctuation of linear statistics of eigenvalues of circulant, symmetric circulant, reverse circulant and Hankel matrices. We show that the linear spect…

A New Approach to Pólya Urn Schemes and Its Infinite Color Generalization

Antar Bandyopadhyay, Debleena Thacker

In this work we generalize Polya urn schemes with possibly infinitely many colors and extend the earlier models described in [4, 5, 7]. We provide a novel and unique approach of re…

Subdiffusivity of a random walk among a Poisson system of moving traps on $Z$

Siva Athreya, Alexander Drewitz, Rongfeng Sun

We consider a random walk among a Poisson system of moving traps on $Z$ . In earlier work [DGRS12], the quenched and annealed survival probabilities of this random walk ha…

Ruin probabilities under Sarmanov dependence structure

Krishanu Maulik, Moumanti Podder

Our work aims to study the tail behaviour of weighted sums of the form $\sum_{i = 1}^{\infty} X_{i} \prod_{j = 1}^{i} Y_{j}$ , where $(X_{i}, Y_{i})$ are independent and identically dist…
