These lack the discrete set of regular eigenmodes that are found in classical wave systems governed by an elliptic equation. In most 2D hyperbolic cases the discrete eigenmodes are replaced by a continuous spectrum of wave fields that possess a self-similar spatial structure and have a (point, line or planar) singularity in the interior. These singularities are called wave attractors because they form the attracting limit set of an iterated nonlinear map, which is employed in constructing exact solutions of this hyperbolic equation. While this is an inviscid, ideal fluid result, observations support the physical relevance of wave attractors by showing localization of wave energy onto their predicted locations. It is shown that in 3D, wave attractors may co-exist with a regular kind of trapped wave. Wave attractors are argued to be of potential relevance to fluids that are density-stratified, rotating, or subject to a magnetic field (or a combination of these) all of which apply to geophysical media.<\/jats:p>","DOI":"10.1142\/s0218127405013733","type":"journal-article","created":{"date-parts":[[2005,10,26]],"date-time":"2005-10-26T11:55:00Z","timestamp":1130327700000},"page":"2757-2782","source":"Crossref","is-referenced-by-count":70,"title":["WAVE ATTRACTORS: LINEAR YET NONLINEAR"],"prefix":"10.1142","volume":"15","author":[{"given":"LEO R.
