A Levy Khintchine type representation of convolution semigroups on commutative hypergroups
A Levy Khintchine type representation convolution semigroups commutative hypergroups
2009/9/22
We first study L6vy measures, Poisson and Gaussian
convolution semigroups on commutative hypergroups. Then we present
a Lbvy-Khintchine type representation of a convolution semigroup
(pJ,,, with sy...
A representation theorem for continuous additive functionals of zero quadratic variation
A representation theorem continuous additive functionals zero quadratic variation
2009/9/22
We study continuous additive functionals of zero
quadratic variation of strong Markov continuous local martingales by
means of stochastic calculus. We show that they admit a representation
as a sto...
Martin representation for alpha-harmonic functions
Martin representation alpha-harmonic functions
2009/9/22
Let D be a nonempty open bounded subset of
d 2 2, and let 0 < a c 2. For a-harmonic functions on D vanishing
outside D an analogue of the Martin representation for harmonic functions
is derived.

A variational representation for positive functionals of
a Hilbert space valued Wiener process (w(.)is) p roved. This representation
is then used to prove a large deviations principle for the family...
Spectral representation and extrapolation of stationary random processes on linear spaces
Spectral representation extrapolation of stationary random processes linear spaces
2009/9/21
The paper deals with continuous Banach-space-valued
stationary random processes on linear spaces. From von Waldenfels'
1131 integral representation of positive definite functions on a linear
space ...
A REPRESENTATION OF EXCESSIVE FUNKTIONS AS EXPECTED SUPREMA
Markov processes excessive functions expected suprema
2009/9/18
For a nice Markov process such as Brownian motion
on a domain in Rd, we prove a representation of excessive functions in
terms of expected suprema This is motivated by recent work of El
Karoui [S] ...
Classification with minimax fast rates for classes of Bayes rules with sparse representation
Classification Sparsity Decision dyadic trees Minimax rates Aggregation
2009/9/16
We consider the classification problem on the cube $[0,1]^d$ when the Bayes rule is known to belong to some new functions classes. These classes are made of prediction rules satisfying some conditions...
Martingale Representation and a Simple Proof of Logarithmic Sobolev Inequalities on Path Spaces
Martingale Representation Logarithmic Sobolev Inequality Hypercontractivity PathSpace
2009/5/8
We show how the Clark-Ocone-Haussmann formula for Brownian motion on a compact Riemannian manifold put forward by S. Fang in his proof of the spectral gap inequality for the Ornstein-Uhlenbeck operato...
A Representation for Non-Colliding Random Walks

2009/4/29
We define a sequence of mappings $Gamma_k:D_0(R_+)^kto D_0(R_+)^k$ and prove the following result: Let $N_1,ldots,N_n$ be the counting functions of independent Poisson processes on $R_+$ with respecti...

2009/4/24
We study some probabilistic representations, based on branching processes, of a simple nonlinear differential equation, i.e. $u'=lambda u(au^R-1)$. The first approach is basically the same used by Le ...

GRAPHICAL REPRESENTATION OF SOME DUALITY RELATIONS IN STOCHASTIC POPULATION MODELS

2009/3/27
We derive a unified stochastic picture for the duality of a resampling-selection model with a branching-coalescing particle process (cf. MR2123250) and for the self-duality of Feller's branching diffu...

Asymptotic Representation of Ratio Statistics and Their Mean Squared Errors
asymptotic mean squared error asymptotic U-statistics bias correction coefficient of variation correlation coefficient H-decomposition
2009/3/9
Some statistics in common use take a form of a ratio of two statistics such as sample correlation coefficient, Pearson’s coefficient of variation and so on. In this paper, obtaining an asymptotic repr...

Suppose the data consist of a set S of points xj , 1 ≤ j ≤ J, distributed in a
bounded domain D RN, where N is a large number. An algorithm is given
for finding the sets Lk of dimension k N, k = 1, ...
