Erdős–Rényi Poissonized [PDF]

open access: diamondComptes Rendus. Mathématique
We introduce a variant of the Erdős–Rényi random graph where the number of vertices is random and follows a Poisson law. A very simple Markov property of the model entails that the Lukasiewicz exploration is made of independent Poisson increments. Using a vanilla Poisson counting process, this enables us to give very short proofs of classical results ...

Sharp Rosenthal‐type inequalities for mixtures and log‐concave variables

open access: yesBulletin of the London Mathematical Society, Volume 55, Issue 3, Page 1222-1239, June 2023., 2023
Abstract We obtain Rosenthal‐type inequalities with sharp constants for moments of sums of independent random variables which are mixtures of a fixed distribution. We also identify extremizers in log‐concave settings when the moments of summands are individually constrained.

Multitime Distribution in Discrete Polynuclear Growth

open access: yesCommunications on Pure and Applied Mathematics, Volume 74, Issue 12, Page 2561-2627, December 2021., 2021
Abstract We study the multitime distribution in a discrete polynuclear growth model or, equivalently, in directed last‐passage percolation with geometric weights. A formula for the joint multitime distribution function is derived in the discrete setting. It takes the form of a multiple contour integral of a block Fredholm determinant.

The number of distinct part sizes of some multiplicity in compositions of an Integer. A probabilistic Analysis [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2003
Random compositions of integers are used as theoretical models for many applications. The degree of distinctness of a composition is a natural and important parameter. A possible measure of distinctness is the number $X$ of distinct parts (or components).

A New Binomial Recurrence Arising in a Graphical Compression Algorithm [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
In a recently proposed graphical compression algorithm by Choi and Szpankowski (2009), the following tree arose in the course of the analysis. The root contains n balls that are consequently distributed between two subtrees according to a simple rule: In

Poisson Autoregression [PDF]

open access: yesJournal of the American Statistical Association, 2008
This paper considers geometric ergodicity and likelihood based inference for linear and nonlinear Poisson autoregressions.In the linear case the conditional mean is linked linearly to its past values as well as the observedvalues of the Poisson process.

On the Number of 2-Protected Nodes in Tries and Suffix Trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
We use probabilistic and combinatorial tools on strings to discover the average number of 2-protected nodes in tries and in suffix trees. Our analysis covers both the uniform and non-uniform cases.

Analysis of the multiplicity matching parameter in suffix trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
In a suffix tree, the multiplicity matching parameter (MMP) $M_n$ is the number of leaves in the subtree rooted at the branching point of the $(n+1)$st insertion.

A complement to Le Cam's theorem [PDF]

open access: yes, 2007
This paper examines asymptotic equivalence in the sense of Le Cam between density estimation experiments and the accompanying Poisson experiments. The significance of asymptotic equivalence is that all asymptotically optimal statistical procedures can be
