内容摘要：

In this talk we discuss the wellposedness and large time behavior of strong solutions for the compressible Oldroyd-B model. Exploiting the harmonic analysis tools, we prove first that the problem is globally well-posed for small initial data in spaces with low regularity. Then, we obtain the optimal decay rates under some suitable condition involving only the low frequency of the initial data.
