Energy-conserving numerical methods for multi-symplectic Hamiltonian PDEs
Energy-conserving numerical methods Hamiltonian PDEs
2012/8/8
In this paper, the discrete gradient methods are investigated for ODEs with 痳st integral,
and the recursive formula is presented for deriving the high-order numerical methods. We
generalize the idea...

In this paper, we investigate multi-symplectic Runge-Kutta-Nystr膐m (RKN) methods for non-
linear Schr膐dinger equations. Concatenating symplecitc Nystr膐m methods in spatial direct...
Generating Functions of Multi-symplectic PRK Methods via DW Hamilton-Jacobi Equations
Multi-Symplectic Partitioned Runge-Kutta Methods Generating Functions DW

In this paper we investigate Donder-Weyl (DW) Hamilton-Jacobi equations and establish the
connection between DW Hamilton-Jacobi equations and multi-symplectic Hamiltonian systems.
Based on the study...
