A topological proof of Sklar’s theorem in arbitrary dimensions

open access: yesDependence Modeling, 2022
Copulas are appealing tools in multivariate probability theory and statistics. Nevertheless, the transfer of this concept to infinite dimensions entails some nontrivial topological and functional analytic issues, making a deeper theoretical understanding

Polymer Measure: Varadhan's Renormalization Revisited [PDF]

open access: yes, 2014
Through chaos decomposition we improve the Varadhan estimate for the rate of convergence of the centered approximate self-intersection local time of planar Brownian motion.Comment: 5 ...

Self-avoiding fractional Brownian motion - The Edwards model [PDF]

open access: yes, 2010
In this work we extend Varadhan's construction of the Edwards polymer model to the case of fractional Brownian motions in $\R^d$, for any dimension $d\geq 2$, with arbitrary Hurst parameters $H\leq 1/d$.Comment: 14 ...

Well-posed Bayesian inverse problems and heavy-tailed stable quasi-Banach space priors [PDF]

open access: yes, 2016
This article extends the framework of Bayesian inverse problems in infinite-dimensional parameter spaces, as advocated by Stuart (Acta Numer. 19:451--559, 2010) and others, to the case of a heavy-tailed prior measure in the family of stable distributions,

The Gaussian Radon Transform in Classical Wiener Space [PDF]

open access: yes, 2014
We study the Gaussian Radon transform in the classical Wiener space of Brownian motion. We determine explicit formulas for transforms of Brownian functionals specified by stochastic integrals.

Intersection local times of independent fractional Brownian motions as generalized white noise functionals [PDF]

open access: yes, 2010
In this work we present expansions of intersection local times of fractional Brownian motions in $\R^d$, for any dimension $d\geq 1$, with arbitrary Hurst coefficients in $(0,1)^d$.

Some Fine Properties of BV Functions on Wiener Spaces

open access: yesAnalysis and Geometry in Metric Spaces, 2015
In this paper we define jump set and approximate limits for BV functions on Wiener spaces and show that the weak gradient admits a decomposition similar to the finite dimensional case.

Intersection local times of fractional Brownian motions with $H\in(0,1)$ as generalized white noise functionals [PDF]

open access: yes, 2008
In $\R^d$, for any dimension $d\geq 1$, expansions of self-intersection local times of fractional Brownian motions with arbitrary Hurst coefficients in $(0,1)$ are presented.
