DESCRIPTION:Title: <a href="https://researchseminars.org/talk/WOW/11/">Lar
 ge-amplitude solitary waves for the Whitham equation</a>\nby Erik Wahlen (
 Lund University) as part of Waves in One World (WOW) series\n\n\nAbstract\
 nIn the 1960’s G. B. Whitham suggested a non-local version of the KdV eq
 uation as a model for water waves. Unlike the KdV equation it is not integ
 rable\, but it has certain other advantages. In particular\, it has the sa
 me dispersion relation as the full water wave problem and it allows for wa
 ve breaking. The existence of a highest\, cusped periodic wave was recentl
 y proved using global bifurcation theory. I will discuss the same problem 
 for solitary waves. This presents several new challenges.\n\nJoint work wi
 th T. Truong (Lund) and M. Wheeler (Bath).\n
