布朗运动的退化Einstein模型的迭代能量估计

An Iterative Energy Estimate for Degenerate Einstein model of Brownian motion

Isanka Garli Hevage, Akif Ibraguimov, Zeev Sobol

摘要:

考虑退化的爱因斯坦布朗运动模型,当运动粒子在碰撞前的时间间隔,与在时间t的观测点x处单位体积的粒子数u(x,t)成倒数时.当u接近0时,控制流体特性的参数0 < tau < C几乎无限制地增加。这种退化导致介质中颗粒分布的局部化。本文给出了这些自由跳跃的时间间隔和频率作为u的函数的一个结构条件,它保证了u的有限传播速度。

英文摘要:

We consider the degenerate Einsteins Brownian motion model when the time interval of the moving particles before the collisions, is reciprocal to the number of particles per unit volume u(x,t), at the point of observation x at time t. The parameter 0 < tau < C, which controls the characteristics of the fluid, almost increases unboundedly, as u approaches 0. This degeneration leads to the localization of the particle distribution in the media. In the paper, we present a structural condition of the time interval and the frequency of these free jumps, as functions of u which guarantees the finite speed of propagation of u.
