本文研究在边界上有弹性碰撞的半无限系统中理想气体中重质量的运动。运动是由弹性碰撞决定的。我们证明了在布朗运动中,重粒子的位置和速度过程的收敛极限为速度和位置保持耦合的扩散过程。
We consider the motion of a heavy mass in an ideal gas in a semi-infinite system, with elastic collisions at the boundary. The motion is determined by elastic collisions. We prove in the Brownian motion limit the convergence of the position and velocity process of the heavy particle to a diffusion process in which velocity and position remain coupled.
