This work is conceed with e1-error estimates on a Hamiltonian-preserving scheme for the Liouville equation with piecewise constant potentials in one space dimen
The extended discrete gradient method is an extension of traditional discrete gradient method,which is specially designed to solve oscillatory Hamiltonian syste
A new polynomial formulation of variable step size linear multistep methods is presented,where each k-step method is characterized by a fixed set of k-1 or k pa
