具有部分BMO系数的Stokes方程组的加权$L_q$ -估计

Weighted $L_q$-estimates for stationary Stokes system with partially BMO coefficients

Hongjie Dong, Doyoon Kim

摘要:

证明了当系数是部分BMO函数时,有界Reifenberg平坦区域上的定常Stokes系统的解在索伯列夫空间中的唯一可解性,即,局部地,它们仅在一个方向上是可测量的,并且在其它方向上具有小的平均振荡。利用这个结果,我们建立了Reifenberg平坦区域上部分BMO系数系统在Muckenhoupt型加权索伯列夫空间中的唯一可解性.我们还提出了加权先验$L_q$ -估计的系统时,域是整个欧几里得空间或半空间。

英文摘要:

We prove the unique solvability of solutions in Sobolev spaces to the stationary Stokes system on a bounded Reifenberg flat domain when the coefficients are partially BMO functions, i.e., locally they are merely measurable in one direction and have small mean oscillations in the other directions. Using this result, we establish the unique solvability in Muckenhoupt type weighted Sobolev spaces for the system with partially BMO coefficients on a Reifenberg flat domain. We also present weighted a priori $L_q$-estimates for the system when the domain is the whole Euclidean space or a half space.
