报告题目: Dispersive effect and global well-posedness of the compressible viscoelastic fluids

报告摘要: This talk is concerned with the global well-posedness issue of the compressible viscoelastic fluids in the whole space RN,N>=2. The proof relies on the dispersive estimates to the linearized hyperbolic system combined with energy estimates to the hyperbolic- parabolic system.  By exploiting the intrinsic structure of the system under some physical restrictions, we find that the compressible viscoelastic fluids admits a unique global solution with a class of large initial data in the sense of critical L2 framework. This was a joint work with Dr. Bin Han in Hangzhou Dianzi University.
