Inner structure of Gauss-Bonnet-Chern Theorem and the Morse theory
Yi-shi Duan, Peng-ming Zhang
We define a new one form H^A based on the second fundamental tensor H^abA, the Gauss-Bonnet-Chern form can be novelly expressed with this one-form. Using the phi-mapping theory we…
Decomposing the SU(N) Connection and the Wu-Yang Potential
Yi-shi Duan, Peng-ming Zhang
Based on the decomposition of SU(2) gauge field, we derive a generalization of the decomposition theory for the SU(N) gauge field. We thus obtain the invariant electro-magnetic ten…
The configuration of a topological current and physical structure: an application and paradigmatic evidence
Li-Bin Fu, Jie Liu, Shi-Gang Chen +1
In the -mapping theory, the topological current constructed by the order parameters can possess different inner structure. The difference in topology must correspond to the diff…
Spinor Decomposition of SU(2) Gauge Potential and The Spinor Structures of Chern-Simons and Chern Density
Yi-shi Duan, Xin Liu, Li-bin Fu
In this paper, the decomposition of SU(2) gauge potential in terms of Pauli spinors is studied. Using this decomposition, the spinor strutures of the Chern-Simons form and the Cher…
