by introducing characteristics
the two-component Degasperis-Procesi systems are transformed into an ODE system. Next
applying the classic well-posedness theory to the solution of ordinary differential equations
the local existence and uniqueness of the solution to the ODE system are obtained. Finally
the local existence and uniqueness of the solution for the two-component Degasperis-Procesi system are investigated. And the conclusion of the weak continuous dependence on initial conditions is proven.
