Snakes and perturbed random walks
Gopal Basak, Stanislav Volkov
In this paper we study some properties of random walks perturbed at extrema, which are generalizations of the walks considered e.g., in Davis (1999). This process can also be viewe…
Brownian Web and Oriented Percolation: Density Bounds
Anish Sarkar, Rongfeng Sun
In a recent work, we proved that under diffusive scaling, the collection of rightmost infinite open paths in a supercritical oriented percolation configuration on the space-time la…
Limiting Spectral Distribution of Block Matrices with Toeplitz Block Structure
Riddhipratim Basu, Arup Bose, Shirshendu Ganguly +1
We study two specific symmetric random block Toeplitz (of dimension ) matrices: where the blocks (of size ) are (i) matrices with i.i.d. entries, and (ii) a…
Joint convergence of several copies of different patterned random matrices
Riddhipratim Basu, Arup Bose, Shirshendu Ganguly +1
We study the joint convergence of independent copies of several patterned matrices in the noncommutative probability setup. In particular, joint convergence holds for the well know…
Limiting spectral distribution of sample autocovariance matrices
Anirban Basak, Arup Bose, Sanchayan Sen
We show that the empirical spectral distribution (ESD) of the sample autocovariance matrix (ACVM) converges as the dimension increases, when the time series is a linear process wit…
Effect of truncation on large deviations for heavy-tailed random vectors
Arijit Chakrabarty
This paper studies the effect of truncation on the large deviations behavior of the partial sum of a triangular array coming from a truncated power law model. Each row of the trian…
