Discrete total variation calculus and Lee's discrete mechanics
نویسندگان
چکیده
A discrete total variation calculus is presented in this paper. Using this calculus, we prove that the solution of the system of difference equations in Lee s discrete mechanics preserves a symplectic structure in the space–time sense. Numerical experiments are also reported. 2005 Elsevier Inc. All rights reserved.

Total Variation and Variational Symplectic-Energy- Momentum integrators
In 1980’s, Lee proposed an energy-preserving discrete mechanics with variable time steps by taking (discrete) time as dynamical variable [2, 3, 4]. On the other hand, motivated by the symplectic property of Lagrangian mechanics, a version of discrete Lagrangian mechanics has been devoloped and variational integrators that preserve discrete symplectic two form have been obtained [11, 12, 15, 16,...
متن کاملThe comparison of two high-order semi-discrete central schemes for solving hyperbolic conservation laws
This work presents two high-order, semi-discrete, central-upwind schemes for computing approximate solutions of 1D systems of conservation laws. We propose a central weighted essentially non-oscillatory (CWENO) reconstruction, also we apply a fourth-order reconstruction proposed by Peer et al., and afterwards, we combine these reconstructions with a semi-discrete central-upwind numerical flux ...

متن کاملDiscrete Calculus of Variation for Homographic Configurations in Celestial Mechanics
We provide in this paper the discrete equations of motion for the newtonian n-body problem deduced from the quantum calculus of variations (Q.C.V.) developed in [3, 4, 7, 8]. These equations are brought into the usual lagrangian and hamiltonian formulations of the dynamics and yield sampled functional equations involving generalized scale derivatives. We investigate especially homographic solut...
