Traveling Waves with Multi-Valued Height
To participate in this seminar, please register here: https://www.msri.org/seminars/25657
A family of exact pure capillary traveling waves, the Crapper waves, contains waves for which the height of the surface is not a graph with respect to the horizontal (i.e., the height is multi-valued). Many existence theories for traveling water waves, however, make an explicit assumption that height is single-valued. While traveling irrotational gravity water waves might not overturn, in more general settings, this assumption of single-valued height is unnecessarily restrictive. We report progress on two fronts for existence theory for traveling waves with multi-valued height: perturbation results for the Crapper waves which demonstrate that there exist traveling waves with multi-valued height beyond the pure capillary setting, and development and implementation of a formulation for traveling waves which does not restrict to single-valued height and which is suitable for use in both the two-dimensional and three-dimensional settings.
