| Outline of Final Research Achievements |
Put two heavy particles into an ideal gas environment, a system consists of infinitely many light particles with a certain initial distribution, and assume that the interactions between particles are non-random. In this research, the interactions between the heavy particles and the light particles are assumed to be of same type. We are interested in the problem of the limit behaviors of the heavy particles when the mass of the light particles converges to 0, under different settings.
We considered the stochastic differential equations corresponding to the cases with or without relative efficacy for the behaviors of heavy particles, and proved the convergences of the corresponding stochastic processes. This gives us the concrete expressions of the only candidate limit processes for each case. Also, we proved the convergence of the particle-environment model to this candidate for the case with relative efficacy.
