报告摘要：

In this paper, we investigate the initial-boundary-value problem for a compressible viscoelastic fluid in half space R3+. As demonstrated in our previous work, the solution fails to maintain full regularity in standard Sobolev spaces, which can be attributed to the characteristic boundary structure. To address this issue, we consider an anisotropic weighted Sobolev space, where the order of partial differentiation in the normal direction is half of that in the tangential direction. Subsequently, we prove that the aforementioned initial- boundary-value problem is globally well-posed within this anisotropic Sobolev space.
