Some existence and uniqueness results of solutions to its Cauchy problem were established for large initial data under various circumstances [see, for example, Perthame, B., “Global existence to the BGK model of Boltzmann equation,” J. Differ. Equations 82, 191–205 (1989)]. In this paper, by establishing some weighted Lp estimates of the hydrodynamical quantities of a gas, we prove the existence theorem of the Lp solutions to the Cauchy problem and establish the propagation properties of the Lp moments for this kind of solutions.Read More
