The MWF method for kinetic models: An overview and research perspective
No full textany physical or biological phenomena deal with the dynamics of interacting
particles (of inert matter or living being). These classes of phenomena are well
described in physics using a kinetic approach based on Boltzmann equation and
in biology with a generalized kinetic theory (kinetic theory for active particles).
In general, the analytical solutions of the related models are missing thus become
extremely relevant the development of numerical approaches. The particle method
are a class of numerical methods used to find a numerical solution of Boltzmann
equations. The MWF-method for kinetic equations was firstly proposed by S.
Motta and J. Wick in 1992 and recently generalized for the equations system case.
The aim of this talk is to overview the method and its applications in biology,
physics and astronomy

The MWF Method: a Convergence Theorem for HomogenousOne-Dimensional Case
No full textAbstractThe MWF numerical method for kinetic equations was presented by S. Motta and J. Wick in 1992 and recently extended by the authors to systems of kinetic equations. The basic idea of the method consists in rewriting the kinetic equation in a conservation law in divergence form, redefining the collisions as a flux and formally to transform the problem into a collisionless one. In all tested cases, the numerical results are in agreement with the exact solutions but a convergence proof of the method, to the best of our knowledge, is missing.In this paper we present our investigation on the sufficient conditions that the collision operator may satisfy, to guarantee a convergence proof of the method in the homogeneous one-dimensional case. This investigation is of both theoretical and applied interest
The MWM Method for Kinetic Equations Systems
No full textAbstractMany physical or biological phenomena deal with the dynamics of interacting entities. These class of phenomena are well described in physics, using a kinetic approach based on Boltzmann equation. A Generalized Kinetic theory has been proposed to extend this approach to biological scenarios. An analytical solution of Boltzmann equation can be found only in very simple cases, so numerical methods become extremely relevant. The particle method is a class of numerical methods used to find a numerical solution of Boltzmann equations. The MWF-method for kinetic equations was firstly proposed by S. Motta and J. Wick in 1992. Here, we show that the MWF-method can be extended to system of Boltzamm equations
