Derivation of Lagrangian density for the "good" Boussinesq equation and multisymplectic disretizations
نویسندگان
چکیده
The Lagrangian density for the ‘‘good’’ Boussinesq equation is derived by introducing a new variable in this paper. Based on this density, we consider the corresponding multisymplectic formulation and discretizations. Numerical experiments are also reported. 2008 Elsevier Inc. All rights reserved.

Multisymplectic geometry, covariant Hamiltonians, and water waves
This paper concerns the development and application of the multisymplectic Lagrangian and Hamiltonian formalism for nonlinear partial differential equations. This theory generalizes and unifies the classical Hamiltonian formalism of particle mechanics as well as the many pre-symplectic 2-forms used by Bridges. In this theory, solutions of a partial differential equation are sections of a fibre ...
متن کاملExistence and blow-up of solution of Cauchy problem for the sixth order damped Boussinesq equation
In this paper, we consider the existence and uniqueness of the global solution for the sixth-order damped Boussinesq equation. Moreover, the finite-time blow-up of the solution for the equation is investigated by the concavity method.
متن کاملOn Symplectic and Multisymplectic Srtuctures and Their Discrete Versions in Lagrangian Formalism
We introduce the Euler-Lagrange cohomology to study the symplectic and multisymplectic structures and their preserving properties in finite and infinite dimensional Lagrangian systems respectively. We also explore their certain difference discrete counterparts in the relevant regularly discretized finite and infinite dimensional Lagrangian systems by means of the difference discrete variasional...
متن کاملDerivation of the multisymplectic Crank-Nicolson scheme for the nonlinear Schrödinger equation
The Crank–Nicolson scheme as well as its modified schemes is widely used in numerical simulations for the nonlinear Schrödinger equation. In this paper, we prove the multisymplecticity and symplecticity of this scheme. Firstly, we reconstruct the scheme by the concatenating method and present the corresponding discrete multisymplectic conservation law. Based on the discrete variational principl...
متن کاملGenerating Functionals and Lagrangian PDEs
The main goal of this paper is to derive an alternative characterization of the multisymplectic form formula for classical field theories using the geometry of the space of boundary values. We review the concept of Type-I/II generating functionals defined on the space of boundary data of a Lagrangian field theory. On the Lagrangian side, we define an analogue of Jacobi’s solution to the Hamilto...
