Our analysis is based on a method to solve continuum limits of the discrete string equation which uses the resolvent of the Lax operator of the underlying Toda hierarchy. This method also leads to an explicit formulation, in terms of coupling constants and critical parameters, of the members of the Painlevé I and Painlevé II hierarchies associated with one-cut and two-cut critical models, respectively.engjournal articlehttp://iopscience.iop.org/1751-8121/44/28/285206/pdf/1751-8121_44_28_285206.pdfhttp://iopscience.iop.orghttp://arxiv.org/pdf/1106.0593v1.pdfopen access51-73Double Scaling LimitPartition-FunctionQuantum-GravityAsymptoticsUniversalityEquationsPolynomialsBehaviorFísica-Modelos matemáticos
