Asymptotic laws for compositions derived from transformed subordinators [PDF]

open access: yes, 2006
A random composition of $n$ appears when the points of a random closed set $\widetilde{\mathcal{R}}\subset[0,1]$ are used to separate into blocks $n$ points sampled from the uniform distribution. We study the number of parts $K_n$ of this composition and

Trimmed trees and embedded particle systems

open access: yes, 2004
In a supercritical branching particle system, the trimmed tree consists of those particles which have descendants at all times. We develop this concept in the superprocess setting. For a class of continuous superprocesses with Feller underlying motion on

Profile of Bucket Tries

open access: yesپژوهش‌های ریاضی, 2020
Introduction Tries (from retrieval) are one of the most practical data structures with a tree construction in computer science. Tries store string data in leaves of tree.

Testing for a General Class of Functional Inequalities [PDF]

open access: yes, 2013
In this paper, we propose a general method for testing inequality restrictions on nonparametric functions. Our framework includes many nonparametric testing problems in a unified framework, with a number of possible applications in auction models, game ...

The oscillatory distribution of distances in random tries

open access: yes, 2005
We investigate \Delta_n, the distance between randomly selected pairs of nodes among n keys in a random trie, which is a kind of digital tree.

Cover and hitting times of hyperbolic random graphs

open access: yesRandom Structures &Algorithms, Volume 65, Issue 4, Page 915-978, December 2024.
Abstract We study random walks on the giant component of Hyperbolic Random Graphs (HRGs), in the regime when the degree distribution obeys a power law with exponent in the range (2,3)$$ \left(2,3\right) $$. In particular, we first focus on the expected time for a random walk to hit a given vertex or visit, that is, cover, all vertices.

Noncolliding system of continuous-time random walks [PDF]

open access: yes, 2014
The continuous-time random walk is defined as a Poissonization of discrete-time random walk. We study the noncolliding system of continuous-time simple and symmetric random walks on ${\mathbb{Z}}$.

Local limits in p$p$‐adic random matrix theory

open access: yesProceedings of the London Mathematical Society, Volume 129, Issue 3, September 2024.
Abstract We study the distribution of singular numbers of products of certain classes of p$p$‐adic random matrices, as both the matrix size and number of products go to ∞$\infty$ simultaneously. In this limit, we prove convergence of the local statistics to a new random point configuration on Z$\mathbb {Z}$, defined explicitly in terms of certain ...

Studying the properties of galaxy cluster morphology estimators

open access: yes, 2012
X-ray observations of galaxy clusters reveal a large range of morphologies with various degrees of disturbance, showing that the assumptions of hydrostatic equilibrium and spherical shape which are used to determine the cluster mass from X-ray data are ...

Asymptotic expansions relating to the distribution of the length of longest increasing subsequences

open access: yesForum of Mathematics, Sigma
We study the distribution of the length of longest increasing subsequences in random permutations of n integers as n grows large and establish an asymptotic expansion in powers of $n^{-1/3}$ .
