Lagrangian, Hamiltonian and other Structures for the Heat Equation and Potential Burgers Equation
Miguel D. Bustamante, Sergio A. Hojman
In this work, we construct the general solution to the Heat Equation (HE) and to many tensor structures associated to the Heat Equation, such as Symmetries, Lagrangians, Poisson Br…

Non-standard Construction of Hamiltonian Structures and of the Hamilton-Jacobi equation
M. Herrera, S. A. Hojman
Examples of non-standard construction of Hamiltonian structures for dynamical systems and the respective Hamilton-Jacobi (H-J) equations, without using Lagrangians, are presented.…

Non-Lagrangian Construction of Hamiltonian Structures
Sergio A. Hojman
A method to construct Hamiltonian theories for systems of both ordinary and partial differential equations is presented. The knowledge of a Lagrangian is not at all necessary to ac…
