On Symplectic, Multisymplectic Structures-Preserving in Simple Finite Element Method
Han-Ying Guo, Xiao-mei Ji, Yu-Qi Li +1
By the simple finite element method, we study the symplectic, multisymplectic structures and relevant preserving properties in some semi-linear elliptic boundary value problem in o…
