Copula function’s concentration set and its concentrated partition
Copula function local correlation structure concentration set concentration measure
2016/1/20
The research on the local correlation structure of copula function is an attractive topic.This paper investigates bivariate copula function’s local correlation structure by defining its concentration ...
Conditioned Poisson distributions and the concentration of chromatic numbers
Random graph chromatic number second moment method categorical data twoway tables Poisson counts
2011/10/9
Abstract: The paper provides a simpler method for proving a delicate inequality that was used by Achlioptis and Naor to establish asymptotic concentration for chromatic numbers of Erdos-Renyi random g...
On the concentration properties of Interacting particle processes
Concentration properties Feynman-Kac particle processes stochastic particle models
2011/9/1
Abstract: These lecture notes present some new concentration inequalities for Feynman-Kac particle processes. We analyze different types of stochastic particle models, including particle profile occup...
Concentration of points on Modular Quadratic Forms

Let Q(x, y) be a quadratic form with discriminant D 6= 0. We obtain non trivial upper
bound estimates for the number of solutions of the congruence Q(x, y) ≡ (mod p), where p is
a prime and x, y l...
Concentration of the information in data with log-concave distributions
Concentration entropy log-concave distributions
2011/2/28
A concentration property of the functional −log f(X) is demonstrated,when a random vector X has a log-concave density f on Rn.This concentration property implies in particular an extension of th...
Existence and concentration of solutions for a class of biharmonic equations
Existence and concentration of solutions biharmonic equations
2010/11/22
Some superlinear fourth order elliptic equations are considered. Ground states are proved to exist and to concentrate at a point in the limit. The proof relies on variational methods, where the existe...

Concentration of measure Brownian particles
2010/11/17
We consider a finite or countable collection of one-dimensional Brownian particles whose dynamics at any point in time is determined by their rank in the entire particle system. Using Transportation ...

concentration of measure large deviations quasiconvexity
2010/12/13
We consider a random variable X that takes values in a (possibly infinite-dimensional) topological vector space X. We show that, with respect to an appropriate “normal distance” on X.
Concentration on circles for nonlinear Schrödinger-Poisson systems with unbounded potentials vanishing at infinity
Stationary nonlinear Schrö dinger-Poisson system weighted Sobolev spaces
2010/12/6
The present paper is devoted to weighted Nonlinear Schrödinger- Poisson systems with potentials possibly unbounded and vanishing at infinity. Using a purely variational approach, we prove the exi...

2010/12/9
We show that with respect to the q-Plancherel measure on partitions of size n, the irreducible
characters of an Hecke algebra Hq(Sn) are concentrated around the normalized trace of Hq(Sn). More preci...
We show that the distribution of the first return time τ to the origin, v, of a simple randomwalk on an infinite recurrent graph is heavy tailed and non-concentrated.

The realizations of a Gaussian field are investigated in the limit where its L2-norm is large.

2010/11/30
We characterize generalized Young measures, the so-called DiPerna-Majda measures which are gener-ated by sequences of gradients. In particular, we precisely describe these measures at the boundary of ...
