摘要: We consider the simultaneous diffusion and homogenization limit of linear Boltzmann equation in a periodic medium regime where mean free path is much smaller than lattice constant. The resulting equation, with an averaged matrix that formally obtained by first performing then one. rigorous proof relies on use two-scale limits, combination asymptotic expansion equilibrium profile powers ratio between
