The Relativistic Boltzmann Equation and Two Times [PDF]

open access: yesEntropy, 2020
We discuss a covariant relativistic Boltzmann equation which describes the evolution of a system of particles in spacetime evolving with a universal invariant parameter τ . The observed time t of Einstein and Maxwell, in the presence of interaction,

Probability Turns Material: The Boltzmann Equation [PDF]

open access: yesEntropy
We review, under a modern light, the conditions that render the Boltzmann equation applicable. These are conditions that permit probability to behave like mass, thereby possessing clear and concrete content, whereas generally, this is not the case ...

Global solvability of a nonlinear Boltzmann equation [PDF]

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2022
In this paper, based on the splitting method scheme, the existence and uniqueness theorem on the whole time interval t ∈ [0 ,T ) ,T ≤∞ for the full nonlinear Boltzmann equation in the nonequilibrium case is proved where the intermolecular interactions ...

Lattice Boltzmann Method for the Generalized Black-Scholes Equation

open access: yesAdvances in Mathematical Physics, 2023
In this paper, an efficient lattice Boltzmann model for the generalized Black-Scholes equation governing option pricing is proposed. The Black-Scholes equation is firstly equivalently transformed into an initial value problem for a partial differential ...

Investigating the Numerical solution of the BoltzmannTransport Equation in silicon in Momentum Space Using Computational Systems of Different Dimensions [PDF]

open access: yesمجلة التربية والعلم, 2020
The Boltzmann transport equation is the basic equation for solving the transport of charge carrier (electrons, holes) problems in semiconductor devices. The distribution function has been obtained from the solution of this equation.

On the Periodic Lorentz Gas and the Lorentz Kinetic Equation [PDF]

open access: yes, 2007
We prove that the Boltzmann-Grad limit of the Lorentz gas with periodic distribution of scatterers cannot be described with a linear Boltzmann equation. This is at variance with the case of a Poisson distribution of scatterers, for which the convergence ...

Hybrid Lattice Boltzmann Model for Nonlinear Diffusion and Image Denoising

open access: yesMathematics, 2023
In the present paper, a novel approach for image denoising based on the numerical solution to the nonlinear diffusion equation is proposed. The Perona–Malik-type equation is solved by employing a hybrid lattice Boltzmann model with five discrete ...
