题目:Global mild solutions to the Boltzmann equation in exterior domains

摘要:In the past decades, there have been an extensive studies on the close-to-equilibrium well-posedness theory for the Boltzmann equation in the whole space or on the torus. On the other hand, most of the physical models have boundaries so that the study on the boundary effect has its importance both in mathematics and physics. Although some important progresses have been made recently for the bounded domain case, much less has been known for the exterior domain case, due to the complicated boundary effect and the lack of a nice time decay estimate for the semigroup generated by the linear Boltzmann operator.

In this talk, we will introduce our recent work on the global mild solutions to the Boltzmann equation in exterior domains with Grad's cutoff hard potential and under general boundary conditions. We emphasize that the solution spaces in our work include the three dimensional case which is physically relevant.
