[图书][B] Modeling anomalous diffusion: from statistics to mathematics

W Deng, R Hou, W Wang, P Xu - 2020 - World Scientific
Let us now consider the Fokker-Planck equation, which is a partial differential equation that
describes the time evolution of the PDF of the positions of particles, and was introduced in …

Subdiffusion in the presence of reactive boundaries: A generalized Feynman–Kac approach

T Kay, L Giuggioli - Journal of Statistical Physics, 2023 - Springer
We derive, through subordination techniques, a generalized Feynman–Kac equation in the
form of a time fractional Schrödinger equation. We relate such equation to a functional which …

Bilateral tempered fractional derivatives

MD Ortigueira, G Bengochea - Symmetry, 2021 - mdpi.com
The bilateral tempered fractional derivatives are introduced generalising previous works on
the one-sided tempered fractional derivatives and the two-sided fractional derivatives. An …

Error estimates for backward fractional Feynman–Kac equation with non-smooth initial data

J Sun, D Nie, W Deng - Journal of Scientific Computing, 2020 - Springer
In this paper, we are concerned with the numerical solution for the backward fractional
Feynman–Kac equation with non-smooth initial data. Here we first provide the regularity …

[图书][B] Functional distribution of anomalous and nonergodic diffusion: from stochastic processes to pdes

W Deng, X Wang, D Nie - 2022 - World Scientific
In the beginning of this book, we will introduce some fundamental concepts of probability
theory which is the basis of describing the anomalous and nonergodic processes in the …

focusing on the dynamical behaviors of particles modelled by non-Brownian stochastic …

Numerical algorithms of the two-dimensional Feynman–Kac equation for reaction and diffusion processes

D Nie, J Sun, W Deng - Journal of Scientific Computing, 2019 - Springer
This paper provides a finite difference discretization for the backward Feynman–Kac
equation, governing the distribution of functionals of the path for a particle undergoing both …

[PDF][PDF] Normal and Anomalous Diffusion in Heterogeneous and Bounded Domains: Lattice Random Walks and Brownian Local Time Approaches

T Kay - 2024 - research-information.bris.ac.uk
Diffusion is a ubiquitous transport mechanism across countless natural and synthetic
systems. In many of these systems the spatial domain is not homogeneous and often …
