Abstract:
This talk will be an introduction and survey of the mysteries of the Korteweg-deVries equations (KdV). KdV was originnaly formulated in 1895 to model the long-time behavior of certain water waves on canals. It succeeded in "predicting" the "great waves of translation" first described by John Scott Russell in 1844. In the 1960's KdV reappeared in the attempt to understand numerical simulations of certain phenomena in atomic physics, simulations that unexpextedly did not show the expected "equipartition of energy". Matematical investigation of those simulations spurred many preogressively more "pure" mathematical investigations of "completely intergrable systems" as well as a theory of "non-linear Fourier transfors" which turned out to be useful for problems in fiber optics and in ocean waves.
