A note on the dispersionless Dym hierarchy
The authors consider the dispersionless Dym hierarchy; in particular, the Miura map that relates it to the dispersionless modified KP hierarchy, and its bi-Hamiltonian structure. They then consider a truncated dispersionless Dym hierarchy (in two variables). This leads to two sets of commuting flows, which the authors show can be derived from the genus-zero topological recursion relation in the Landau-Ginzburg formulation.
