The Euler-Lagrange Cohomology Groups on Symplectic Manifolds
Han-Ying Guo, Jianzhong Pan, Ke Wu +1
The definition and properties of the Euler-Lagrange cohomology groups , , on a symplectic manifold are given and studied. F…
Total Variation and Variational Symplectic-Energy-Momentum integrators
Jing-Bo Chen, Han-Ying Guo, Ke Wu
A discrete total variation calculus with variable time steps is presented in this letter. Using this discrete variation calculus, we generalize Lee's discrete mechanics and derive…
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…
Two Particle Physics Models With Spontaneous CP Violation From Gauge Theory On Discrete Group
Han-Ying Guo, Ke Wu, Chi Xiong
Based on the differential calculus and the gauge theory on discrete groups, we reconstruct two physics models with spontaneous CP violation: (1) The Georgi-Glashow-Lee model with t…
and SUSY Yang-Mills action on non-commutative geometry
Bin Chen, Hong-Bo Teng, Ke Wu
We show that the and SUSY Yang-Mills action can be reformulated in the sense of non-commutative geometry on in a rather simple way. In this…
The -Model and Non-commutative Geometry
Hanying Guo, Jianming Li, Ke Wu +2
In terms of non-commutative geometry, we show that the --model can be built up by the gauge theory on discrete group . We introduce a constraint in the gauge theory, which…
