Continuity of Random Fields on Riemannian Manifolds [PDF]

Asymptotic for the quantization error for a Wiener process with Gaussian starting point [PDF]

open access: yes, 2014
The asymptotics for quantization error for a Wiener process with Gaussian starting point (GSP-Wiener process) is investigated. Using the classical methodology and some analytical approach a first result is obtained.

Necessary and sufficient condition for the smoothness of intersection local time of subfractional Brownian motions

open access: yes, 2011
Let SH and S̃H be two independent d-dimensional sub-fractional Brownian motions with indices H ∈ (0, 1). Assume d ≥ 2, we investigate the intersection local time of subfractional Brownian motions ℓT=∫0T∫0TδStH-S̃sHdsdt,T>0, where δ denotes the Dirac ...

An improved bound for the Gaussian concentration inequality

open access: yes, 2019
In this note, we provide an improved bound for the Gaussian concentration inequality. Our proof is short and bases on the integration-by-parts formula for the gaussian measure.Comment: 4 ...

Brownian Sheet Images and Bessel-Riesz Capacity [PDF]

open access: yesarXiv, 1998
We show that the image of a 2-dimensional set under d-dimensional, 2-parameter Brownian sheet can have positive Lebesgue measure, if and only if the set in question has positive (d/2)-dimensional Bessel-Riesz capacity. Our methods solve a problem of J.-P. Kahane.

Some Comparisons for Gaussian Processes [PDF]

open access: yesProc. Amer. Math. Soc. 128 (2000), 3043-3046, 2000
Extensions and variants are given for the well-known comparison principle for Gaussian processes based on ordering by pairwise distance.

Random processes via the combinatorial dimension: introductory notes [PDF]

open access: yesarXiv, 2004
This is an informal discussion on one of the basic problems in the theory of empirical processes, addressed in our preprint "Combinatorics of random processes and sections of convex bodies", which is available at ArXiV and from our web pages.

On the Brownian meander and excursion conditioned to have a fixed time average [PDF]

open access: yesarXiv, 2006
We study the density of the time average of the Brownian meander/excursion over the time interval [0,1]. Moreover we give an expression for the Brownian meander/excursion conditioned to have a fixed time average.

An arithmetic model for the total disorder process [PDF]

open access: yesarXiv, 2006
We prove a multidimensional extension of Selberg's central limit theorem for the logarithm of the Riemann zeta function on the critical line. The limit is a totally disordered process, whose coordinates are all independent and Gaussian.

Dominos and the Gaussian free field [PDF]

open access: yesarXiv, 2000
We define a scaling limit of the height function on the domino tiling model (dimer model) on simply-connected regions in Z^2 and show that it is the ``massless free field'', a Gaussian process with independent coefficients when expanded in the eigenbasis of the Laplacian.
