All rights reserved.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.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/journal articlehttp://dx.doi.org/10.1016/j.physletb.2005.02.012http://www.sciencedirect.comopen access51-73Tau-functionHierarchiesSymmetriesDimensionsLimitFísica-Modelos matemáticosFísica matemática
