    Title : Traveling waves with multi-valued height
    Abstract : 
         Traveling water waves have been studied for decades, usually with the assumption 
       that the surface is a graph with respect to the horizontal coordinate.  However 
       we know that some waves exist which violate this condition, especially Crapper waves.  
       In work with Akers and Wright, we have reformulated the traveling wave problem 
       to allow interfaces with multi-valued height.  We have applied this framework 
       both analytically and computationally, and will discuss these results including 
       for water waves and interfacial waves, and with surface tension and higher-order 
       hydroelastic effects.
