Noncommutative Differential Calculus and Its Application on Discrete Spaces被引量：3
《Communications in Theoretical Physics》2008年第1期37-44,共8页LIU Zhen BAI Yong-Qiang WU Ke GUO Han-Ying 
The project supported by National Natural Science Foundation of China under Grant No.10626016;China Postdoctor Science Foundation of Henan University under Grant No.05YBZR014
We present the noncommutative differential calculus on the function space of the infinite set and construct a homotopy operator to prove the analogue of the Poincare lemma for the difference complex. Then the horizont...

On General Volume-Preserving Mechanical Systems via Cohomology
《Communications in Theoretical Physics》2003年第5X期595-600,共6页ZHOUBin GUOHan-Ying WUKe 
We present the general form of equations that generate a volume-preserving flow on a symplectic manifold (M,ω) via the highest Euler-Lagrange cohomology.It is shown that for every volume-preserving flow there are som...
