The dynamics of bàll-shaped partiñle with nonuniform surface in the rarefied gas
The model of ball-shaped partiñle with nonuniform active surface in the rarefied gas is constructed. The features of appropriate dynamical system are established. The lemma on the properties of high-dimension ODE is proved. This lemma is an important step, providing an opportunity to find solution corresponding to various types of asymptotic of the partiñle motion.
