Abstract:Some new Hamiltonian canonical system are discussed for a series of partial differential equations in Mathematics and Physics. It includes the Hamiltonian formalism for the symmetry second_order equation with the variable coefficients, the new nonhomogeneous Hamiltonian representation for fourth_order symmetry equation with constant coefficients, the one of MKdV equation and KP equation.
Keywords:infinite dimensional Hamiltonian system  Hamiltonian canonical system  Hamiltonian operator  MKdV (Modified Korteweg_de Vries) equation  KP (Kadomtsev_Petviashvili) equation
