Infinite secret sharing – Examples

open access: yesJournal of Mathematical Cryptology, 2014
The motivation for extending secret sharing schemes to cases when either the set of players is infinite or the domain from which the secret and/or the shares are drawn is infinite or both, is similar to the case when switching to abstract probability ...

Packing-Dimension Profiles and Fractional Brownian Motion [PDF]

open access: yes, 2007
In order to compute the packing dimension of orthogonal projections Falconer and Howroyd (1997) introduced a family of packing dimension profiles ${\rm Dim}_s$ that are parametrized by real numbers $s>0$.

Optimal linear filtering of general multidimensional Gaussian processes and its application to Laplace transforms of quadratic functionals

open access: yesInternational Journal of Stochastic Analysis, Volume 14, Issue 3, Page 215-226, 2001., 2001
The optimal filtering problem for multidimensional continuous possibly non‐Markovian, Gaussian processes, observed through a linear channel driven by a Brownian motion, is revisited. Explicit Volterra type filtering equations involving the covariance function of the filtered process are derived both for the conditional mean and for the covariance of ...

Baxter's inequality for fractional Brownian motion-type processes with Hurst index less than 1/2 [PDF]

open access: yes, 2008
The aim of this paper is to prove an analogue of Baxter's inequality for fractional Brownian motion-type processes with Hurst index less than 1/2. This inequality is concerned with the norm estimate of the difference between finite- and infinite-past ...

Self‐similar processes in collective risk theory

open access: yesInternational Journal of Stochastic Analysis, Volume 11, Issue 4, Page 429-448, 1998., 1998
Collective risk theory is concerned with random fluctuations of the total assets and the risk reserve of an insurance company. In this paper we consider self‐similar, continuous processes with stationary increments for the renewal model in risk theory. We construct a risk model which shows a mechanism of long range dependence of claims.

An approach to the stochastic calculus in the non‐Gaussian case

open access: yesInternational Journal of Stochastic Analysis, Volume 8, Issue 4, Page 361-370, 1995., 1995
We introduce and study a class of operators of stochastic differentiation and integration for non‐Gaussian processes. As an application, we establish an analog of the Itô formula.

Square variation of Brownian paths in Banach spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 5, Issue 3, Page 605-607, 1982., 1982
It is known that if {W(t), 0 ≤ t ≤ 1} is a standard Brownian motion in ℝ then almost surely. We generalize this celebrated theorem of Levy to Brownian motion in real separable Banach spaces.

A note on stability of SPDEs driven by α-stable noises

open access: yesAdvances in Differential Equations, 2014
In this paper, by the Minkovski inequality and the semigroup method we discuss the stability of mild solutions for a class of SPDEs driven by α-stable noise, and the methods are also generalized to deal with the stability of SPDEs driven by subordinated ...

Gaussian lower bounds for the density via Malliavin calculus [PDF]

open access: yes, 2019
In this paper, based on a known formula, we use a simple idea to get a new representation for the density of Malliavin differentiable random variables.

Berry-Esséen bounds and almost sure CLT for quadratic variation of weighted fractional Brownian motion

open access: yesJournal of Inequalities and Applications, 2013
In this paper, using the recent results on Stein’s method combining with Malliavin calculus and the almost sure central limit theorem for sequences of functionals of general Gaussian fields developed by Nourdin and Peccati, we derive the explicit bounds ...
