Baoquan Yuan, Yun Liu

摘要:

本文研究了一类带变形张量阻尼项的不可压缩Oldroyd模型Cauchy问题解的整体存在性和随时间的衰减速率。有三个主要结果。第一个问题是在小初值下解的整体存在性。其次,我们得到了解在$L^{2}-$范数下的时间衰减。最后,得到了高阶Sobolev范数解的时间衰减性.

英文摘要:

This paper investigates the global existence and the decay rate in time of a solution to the Cauchy problem for an incompressible Oldroyd model with a deformation tensor damping term. There are three major results. The first is the global existence of the solution for small initial data. Second, we derive the sharp time decay of the solution in $L^{2}-$norm. Finally, the sharp time decay of the solution of higher order Sobolev norms is obtained.
