Analyticity of the streamlines for periodic traveling free surface water waves with vorticity

Adrian Constantin (Université de Vienne)

The streamlines of periodic irrotational traveling water waves are known to be real-analytic, with exception of the free surface in the case the wave of greatest height which has a corner at the wave crest (the lateral tangents being at an angle of 2\pi/3). The regularity of waves of small and moderate amplitude is, perhaps surprisingly, little affected by the presence of vorticity in the flow. This is joint work with J. Escher.
