00925njm 22002777a 4500 dc Martínez Alonso, Luis author Medina Reus, Elena author 2005-02-24 A class of exact solutions of the dispersionless Toda hierarchy constrained by a string equation is obtained. These solutions represent deformations of analytic curves with a finite number of nonzero harmonic moments. The corresponding tau-functions are determined and the emergence of cusps is studied. 0370-2693 10.1016/j.physletb.2005.02.012 https://hdl.handle.net/20.500.14352/51650 http://dx.doi.org/10.1016/j.physletb.2005.02.012 http://www.sciencedirect.com Exact solutions of integrable 2D contour dynamics
