Optimal regularity for planar mappings of finite distortion (2008)
Astala, Kari, Gill, James, Rohde, Steffen, Saksman, Eero
Let $f:\Omega\to\IR^2$ be a mapping of finite distortion, where $\Omega\subset\IR^2 .$ Assume that the distortion function $K(x,f)$ satisfies $e^{K(\cdot, f)}\in L^p_{loc}(\Omega)$ for some $p>0.$ We...
