摘要

摘要我们研究了无碰撞相对论气体（Jüttner 气体）密度的扩散型方程。扩散传播的速率原来是有限的。我们考虑了这个方程的解的存在性和唯一性问题，以及它的一些广义解。

Diffusion of a collisionless gas

We study a diffusion-type equation for the density of a collisionless relativistic gas (Jüttner gas). The rate of diffusion propagation turns out to be finite. We consider problems of the existence and uniqueness of solutions of this equation, as well as some of its generalized solutions.
