Using the approach of mapping of shape invariant potentials under point canonical transformations, the energy spectra and wave functions are most easily determi
In this paper, we study a finite element scheme of some semi-linear elliptic boundary value problems in high-dhnensjonal space. With uniform mesh, we find that,
In this second papcr of a scries of papers, we explore the differcnce discrete versions for the Euler-Lagrange cohomology and apply them to the symplectic or mu
