摘要:

该文研究了一类非自治的时滞不可压缩非牛顿流体在二维无界区域上的整体适定性. 在外力项具有最低正则性时, 该文结合空间区域分解技术和 Garlekin 方法建立了解的存在性, 然后利用能量估计的方法得到了解的唯一性和稳定性.

关键词: 非牛顿流体, 时滞, 适定性

Abstract:

In this paper, we study the well-poseness of a non-autonomous delayed incompressible non-Newtonian fluid on $2D$ unbounded domains. With a minimal regularity of the force, we prove the existence of solutions by the method of combining the technique of domain decomposition with the Garlerin approximation. Then we use the energy method to prove the uniqueness and the stability of solutions.

Key words: Non-Newtonian fluid, Delay, Well-posedness
