Improved Hölder regularity for strongly elliptic PDEs
Kari Astala, Albert Clop, Daniel Faraco +2
We establish surprising improved Schauder regularity properties for solutions to the Leray-Lions divergence type equation in the plane. The results are achieved by studying the non…

Global smoothness of quasiconformal mappings in the Triebel-Lizorkin scale
Kari Astala, Martí Prats, Eero Saksman
We study quasiconformal mappings in planar domains and their regularity properties described in terms of Sobolev, Bessel potential or Triebel-Lizorkin scales. This leads to opt…
