چکیده
Kahan’s method and a two-step generalisation of the discrete gradient are both linearly implicit methods that can preserve modified energy for Hamiltonian systems with cubic Hamiltonian. These here investigated compared. The schemes applied to Korteweg–de Vries equation Camassa–Holm equation, numerical results presented analysed.

Stabilized Linearly Implicit Simpson-type Schemes for Nonlinear Differential Equations
Abstract: The classical Simpson rule is an optimal fourth order two-step integration scheme for first-order initial-value problems; however, it is unconditionally unstable. An A-stabilized version of Simpson rule was given by Chawla et al [3] and an L-stable version was given by Chawla et al [2]. These rules are functionally implicit, and when applied for the time integration of nonlinear diffe...
متن کاملStructure Preserving Model Reduction of Parametric Hamiltonian Systems
While reduced-order models (ROMs) are popular for approximately solving large 4 systems of differential equations, the stability of reduced models over long-time integration remains 5 an open question. We present a greedy approach for ROM generation of parametric Hamiltonian 6 systems which captures the symplectic structure of Hamiltonian systems to ensure stability of the 7 reduced model. Thro...
متن کاملStructure preserving model reduction of port-Hamiltonian systems
It is shown that by use of the Kalman-decomposition an uncontrollable and/or unobservable port-Hamiltonian system is reduced to a controllable/observable system that inherits a port-Hamiltonian structure. Energy and co-energy variable representations for port-Hamiltonian systems are discussed and the reduction procedures are used for both representations. For a general portHamiltonian system in...
متن کاملStructure-preserving Model Reduction of Forced Hamiltonian Systems
This paper reports a development in the proper symplectic decomposition (PSD) for model reduction of forced Hamiltonian systems. As an analogy to the proper orthogonal decomposition (POD), PSD is designed to build a symplectic subspace to fit empirical data. Our aim is two-fold. First, to achieve computational savings for large-scale Hamiltonian systems with external forces. Second, to simultan...
متن کاملHamiltonian-preserving schemes for the Liouville equation with discontinuous potentials
When numerically solving the Liouville equation with a discontinuous potential, one faces the problem of selecting a unique, physically relevant solution across the potential barrier, and the problem of a severe time step constraint due to the CFL condition. In this paper, We introduce two classes of Hamiltonian-preserving schemes for such problems. By using the constant Hamiltonian across the ...
