The integrable hierarchy and the nonlinear Riemann-Hilbert problem associated with one typical Einstein-Weyl physico-geometric dispersionless system
Abstract
From a specific series of exchange conditions for a one-parameter Hamiltonian vector field, we establish an integrable hierarchy using Lax pairs derived from the dispersionless partial differential equation. An exterior differential form of the integrable hierarchy is introduced, further confirming the existence of the τ function. Subsequently, we present the twistor structure of the hierarchy. By constructing the nonlinear Riemann-Hilbert problem for the equation, the structure of the solution to the equation is better understood.
