Difference Discrete Variational Principle in Discrete Mechanics and Symplectic Algorithm
Xu-Dong Luo, Han-Ying Guo, Yu-Qi Li +1
We propose the difference discrete variational principle in discrete mechanics and symplectic algorithm with variable step-length of time in finite duration based upon a noncommuta…
Difference Discrete Variational Principle,EULER-Lagrange Cohomology and Symplectic, Multisymplectic Structures
H. Y. Guo, Y. Q. Li, K. Wu +1
We study the difference discrete variational principle in the framework of multi-parameter differential approach by regarding the forward difference as an entire geometric object i…
Symplectic, Multisymplectic Structures and Euler-Lagrange Cohomology
H. Y. Guo, Y. Q. Li, K. Wu +1
We study the Euler-Lagrange cohomology and explore the symplectic or multisymplectic geometry and their preserving properties in classical mechanism and classical field theory in L…
Super-Yangian Y(gl(1|1)) and Its Oscillator Realization
G. X. Ju, J. F. Cai, H. Y. Guo +2
On the basis of graded RTT formalism,the defining relation of the super-Yangian Y(gl(1|1)) is derived and its oscillator realization is constructed.
