Global existence and optimal decay of solutions to the incompressible Oldroyd-B model with only stress tensor dissipation and without damping mechanism
Zhi Chen, Weixun Feng, Qiao Liu
We study the -dimensional () incompressible Oldroyd-B model with only stress tensor diffusion and without velocity dissipation as well as the damping mechanism on the st…

Global Regularity and instability for the incompressible non-viscous Oldroyd-B model
Zhi Chen, Weikui Ye, Zhaoyang Yin
In this paper, we consider the 2-dimensional non-viscous Oldroyd-B model. In the case of the ratio equal 1~(), it is a difficult case since the velocity field is no l…
