An integrable dispersionless KdV hierarchy with sources (dKdVHWS) is derived. Lax pair equations and bi-Hamiltonian formulation for dKdVHWS are formulated. A hodograph solution for the dispersionless KdV equation with sources (dKdVWS) is obtained via hodograph transformation. Furthermore, the dispersionless Gelfand–Dickey hierarchy with sources (dGDHWS) is presented. 
On a new generalization of dispersionless Kadomtsev–Petviashvili hierarchy and its reductions
The dispersionless Kadomtsev–Petviashvili hierarchy is generalized by introducing two new time series γn and σk with two parameters ηn and λk. By this hierarchy, we obtain the first type, the second
On the Ablowitz–Ladik equations with self-consistent sources
Darboux transformations and explicit solutions to Ablowitz–Ladik (AL) equations with self-consistent sources (ALESCS) are studied. Based on the Darboux transformation (DT) for the AL problem, we


Hamiltonian Structures for the Generalized Dispersionless KdV Hierarchy
We study from a Hamiltonian point of view the generalized dispersionless KdV hierarchy of equations. From the so-called dispersionless Lax representation of these equations we obtain three compatible
Integrable hierarchies and dispersionless limit
Analogues of the KP and the Toda lattice hierarchy called dispersionless KP and Toda hierarchy are studied. Dressing operations in the dispersionless hierarchies are introduced as a canonical
Solving the dispersionless Dym equation by hodograph transformations
The method of hodograph transformation is used to find a class of exact solutions of the dispersionless Dym (dDym) equation and its reductions. In particular, we discuss hodograph solutions of
Dispersionless limit of integrable models
Nonlinear dispersionless equations arise as the dispersionless limit of well know integrable hierarchies of equations or by construction, such as the system of hydrodynamic type. Some of these
Bi‐Hamiltonian formulation for the Korteweg–de Vries hierarchy with sources
The first Hamiltonian structure is constructed for the Korteweg–de Vries (KdV) hierarchy with sources and for the respective modified systems. Applying the appropriate Miura map the second
