Local Lagrangian Formalism and Discretization of the Heisenberg Magnet Model

D. Karpeev, C. M. Schober

In this paper we develop the Lagrangian and multisymplectic structures of the Heisenberg magnet (HM) model which are then used as the basis for geometric discretizations of HM. Des…

Backward error analysis for multisymplectic discretizations of Hamiltonian PDEs

Alvaro L. Islas, Constance M. Schober

Several recently developed multisymplectic schemes for Hamiltonian PDEs have been shown to preserve associated local conservation laws and constraints very well in long time numeri…
