On Serrin Interior Regularity Criterion for Navier-Stokes Equations

Robin Ming Chen, Giovanni P. Galdi, Bruno Poggi +1

We revisit Serrin's interior spatial regularity criterion for distributional solutions to the Navier-Stokes equations in $R^{3}$ and considerably relax the hypotheses in two…

Failure of CalderÃ³n-Zygmund estimates for degenerate elliptic PDEs with $A_{p}$ -weights when $p > 2$

Armin Schikorra, Martin Ulmer

We use convex integration techniques to provide examples of failure of weighted CalderÃ³n-Zygmund estimates for degenerate linear elliptic PDEs when the weights are in $A_{p}$ , $p >…
