Global existence for the Boltzmann equation in $L^r_v L^\infty_t L^\infty_x$ spaces

Abstract

We study the Boltzmann equation near a global Maxwellian. We prove the global existence of a unique mild solution with initial data which belong to the $L^r_v L^\infty_t L^\infty_x $ spaces where $r \in (1,\infty]$ by using the excess conservation laws and entropy inequality introduced in [5].
