我们考虑了两种不同密度的不可压缩、不可混溶流体在多孔介质中的演化,称为Muskat问题[21],它在二维上类似于Hele - Shaw细胞[24]。对于一类大而单调的初始数据,我们建立了弱解的整体存在性。该证明是基于在空间无穷远处具有特定渐近的初始数据的一个局部适定性结果和图函数一阶导数的一个新的极大原理。©2016 Wiley期刊公司
We consider the evolution of two incompressible, immiscible fluids with different densities in porous media, known as the Muskat problem [21], which in two dimensions is analogous to the Hele‐Shaw cell [24]. We establish, for a class of large and monotone initial data, the global existence of weak solutions. The proof is based on a local well‐posedness result for the initial data with certain specific asymptotics at spatial infinity and a new maximum principle for the first derivative of the graph function.© 2016 Wiley Periodicals, Inc.
