Statistics of non-linear stochastic dynamical systems under L\'evy noises by a convolution quadrature approach

open access: yes, 2011
This paper describes a novel numerical approach to find the statistics of the non-stationary response of scalar non-linear systems excited by L\'evy white noises.

Self-Similarity and Lamperti Convergence for Families of Stochastic Processes

open access: yes, 2010
We define a new type of self-similarity for one-parameter families of stochastic processes, which applies to a number of important families of processes that are not self-similar in the conventional sense. This includes a new class of fractional Hougaard

Markovian nature, completeness, regularity and correlation properties of Generalized Poisson-Kac processes

open access: yes, 2016
We analyze some basic issues associated with Generalized Poisson-Kac (GPK) stochastic processes, starting from the extended notion of the Markovian condition.

Extended Minimal Atomicity through Nondifferentiability: A Mathematical-Physical Approach

open access: yesAdvances in Mathematical Physics, 2019
The mathematical concept of minimal atomicity is extended to fractal minimal atomicity, based on the nondifferentiability of the motion curves of physical system entities on a fractal manifold.

A theoretical framework for the pricing of contingent claims in the presence of model uncertainty

open access: yes, 2006
The aim of this work is to evaluate the cheapest superreplication price of a general (possibly path-dependent) European contingent claim in a context where the model is uncertain.

Calculation of the extended probabilistic box of static voltage stability margin for a hybrid AC-DC power grid with renewables

open access: yesInternational Journal of Electrical Power & Energy Systems
High-order uncertainties arise in the cumulative distribution function parameters of wind speed and solar irradiance due to data gaps and statistical errors in renewable energy stations (RESs).

First-principles prediction of shock Hugoniot curves of boron, aluminum, and silicon from stochastic density functional theory

open access: yesMatter and Radiation at Extremes
By adopting stochastic density functional theory (SDFT) and mixed stochastic–deterministic density functional theory (MDFT) methods, we perform first-principles calculations to predict the shock Hugoniot curves of boron (pressure P = 7.9 × 103–1.6 × 106 ...

Path Integral Quantization and Riemannian-Symplectic Manifolds

open access: yes, 1998
We develop a mathematically well-defined path integral formalism for general symplectic manifolds. We argue that in order to make a path integral quantization covariant under general coordinate transformations on the phase space and involve a genuine ...

Exact expression for the diffusion propagator in a family of time-dependent anharmonic potentials

open access: yes, 1999
We have obtained the exact expression of the diffusion propagator in the time-dependent anharmonic potential $V(x,t)={1/2}a(t)x^2+b\ln x$. The underlying Euclidean metric of the problem allows us to obtain analytical solutions for a whole family of the ...
