First integrals of Lagrange equations for the Cosserat elastic rod dynamics are discussed.Since Lagrange equations of the rod dynamics contain two independent v
As well know, any local regular, analytic and holonomic dynamical systems with finite dimensions can be reduced into Birkhoffian systems, which become self-adjo
Multisymplectic partial differential equations have a sound property of structure preserving, the conservation of multisymplecticity.Multisymplectic integrators
