Lagrangian Approach to Dispersionless KdV Hierarchy

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
We derive a Lagrangian based approach to study the compatible Hamiltonian structure of the dispersionless KdV and supersymmetric KdV hierarchies and claim that our treatment of the problem serves as a very useful supplement of the so-called r-matrix ...
