均匀化和输运方程：沙漠和沙堆的情况
Homogenization and transport equations: the case of desert and sand piles
摘要：
本文建立了沙漠沙丘的短期、平均和长期动态模型。它们是退化的抛物型方程，而且，奇摄动模型。然后，我们给出了模型的存在性和唯一性结果，其次是均匀化的，并给出了一个校正结果。
英文摘要：
In this paper we build models for short-term, mean-term and long-term dynamics of dune in desert. They are models that are degenerated parabolic equations which are, moreover, singularly perturbed. We, then give existence and uniqueness results for the models, followed by homogenization ones and a corrector result is given.
