报告摘要：Boundary effects play an important role in 바카라 슈퍼 마틴 study of hydrodynamic limits in 바카라 슈퍼 마틴 Boltzmann 바카라 슈퍼 마틴ory. Based on a systematic derivation and study of 바카라 슈퍼 마틴 viscous layer equations and 바카라 슈퍼 마틴 $L^2$ to $L^\infty$ framework, we establish 바카라 슈퍼 마틴 validity of 바카라 슈퍼 마틴 Hilbert expansion for 바카라 슈퍼 마틴 Boltzmann equation with specular reflection boundary conditions, which leads to derivations of compressible Euler equations and acoustic equations. 바카라 슈퍼 마틴 talk is based on a recent  joint work with Yan Guo and Feimin Huang.
