摘要:

本文研究 Navier-slip 边界条件下 k-连通区域上的等熵可压缩 Navier-Stokes 方程。作者研究一般区域上稳态系统的多解性,该问题与 Cauchy-Riemann 系统以及区域上调和函数的临界点密切相关。随后基于 Green 函数的结构,在圆形区域上得到交换子估计,并借助共形映射将其推广到一般区域。此外,作者将利用这些结论讨论一般区域上非稳态系统在含真空的大初值条件下的整体适定性与长时间行为。

英文摘要:

This paper investigates the isentropic compressible Navier-Stokes equations on k-connected domains under Navier-slip boundary conditions. We study the multi-solvability of the stationary systems on general domains, which is closely related with the Cauchy-Riemann systems and critical points of harmonic functions on the domain. Then based on the structure of Green's functions, the commutator estimates are obtained on the circular domains and extended to general domains with the help of conformal mappings. Moreover, we will utilize these assertions to discuss the global well-posedness and large time behaviours of the non-stationary systems on general domains with large initial values containing vacuum.
