RT Journal Article T1 Solutions of the dispersionless Toda hierarchy constrained by string equations A1 Martínez Alonso, Luis A1 Medina Reus, Elena AB Solutions of the Riemann-Hilbert problem implementing the twistorial structure of the dispersionless Toda (dToda) hierarchy are obtained. Two types of string equations are considered which characterize solutions arising in hodograph sectors and integrable structures of two-dimensional quantum gravity and Laplacian growth problems.
