Spatial behavior of the solution to the Boltzmann equation with hard sphere

Abstract

The main goal of this thesis is to understand the quantitative spatial behavior of the solution to the Boltzmann equation for hard sphere in the closed to equilibrium setting More precisely we get the quantitative spatial behavior of the solution to the Boltzmann equation under polynomial spatial decay assumption but without any Sobolev regularity assumption on the initial condition
