报告题目:Wellposedness and Large Time Behavior of Solutions to the N-D compressible Oldroyd-B Model


报告地点:理学实验楼312


摘要:In this talk we discuss the wellposedness and large time behavior of strong solutions for the compressible Oldroyd-B model. First, by exploiting the harmonic analysis tools, especially Littlewood-Paley theory, we prove 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.
