Constraint algorithm for k-presymplectic Hamiltonian systems. Application to singular field theories [PDF]
The k-symplectic formulation of field theories is especially simple, since only tangent and cotangent bundles are needed in its description. Its defining elements show a close relationship with those in the symplectic formulation of mechanics. It will be
