$H^{\frac{11}{4}} (R^{2})$ ill-posedness for 2D Elastic Wave system

Xinliang An, Haoyang Chen, Silu Yin

In this paper, we prove that for the 2D elastic wave equations, a physical system with multiple wave-speeds, its Cauchy problem fails to be locally well-posed in $H^{\frac{11}{4}}(…

The Cauchy problems for the 2D compressible Euler equations and ideal MHD system are ill-posed in $H^{\frac{7}{4}} (R^{2})$

Xinliang An, Haoyang Chen, Silu Yin

In a fractional Sobolev space $H^{s} (R^{2})$ with $s \leq \frac{7}{4}$ , we prove the low-regularity ill-posedness for the 2D compressible Euler equations and the 2D ideal compressib…
