Partially supported by MEC project FIS2005-00319A scheme for solving quasiclassical-string equations is developed to prove that genus-zero hitham hierarchies describe the deformations of planar domains determined by rational conformal-maps. This property is applied in normal matrix models to show that deformations of simply-connected supports of eigenvalues under changes of coupling constants are governed by genus-zero Whitham hierarchies.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/journal articlehttp://dx.doi.org/10.1016/j.physletb.2006.08.082http://www.sciencedirect.com/open access51-73Random-matrix ensembleGrowthFluidFlowsFísica-Modelos matemáticosFísica matemática
