Partial analyticity and nodal sets for nonlinear elliptic systems

Analysis of PDEs 2015-06-23 v1

Abstract

We study partial analyticity of solutions to elliptic systems and analyticity of level sets of solutions to nonlinear elliptic systems. We consider several applications, including analyticity of flow lines for bounded stationary solutions to the 2-d Euler equation, and analyticity of water waves with and without surface tension.
