Global Well-Posedness for the 3-D Inviscid Oldroyd-B Model with Fractional Stress Diffusion

Yi Lu, Chen Liang, Zhaoyang Yin

We study the 3-D incompressible inviscid Oldroyd-B model with fractional stress diffusion \((-Δ)^βτ\) and without stress damping. For $\beta \in (\frac{1}{2},1)$ and $s\in [2β+\frac{1}{…
