SO(4) Monopole As A New Topological Invariant And Its Topological Structure
Sheng Li, Yishi Duan
By making use of the decomposition theory of gauge potential, the inner structure of SU(2) and SO(4) gauge theory is discussed in detail. We find the SO(4) monopole can be given vi…

Yishi Duan, Ying Jiang
In Einstein-Cartan theory, by the use of the general Noether theorem, the general covariant angular-momentum conservation law is obtained with the respect to the local Lorentz tran…
The Topological Structure of the Space-Time Disclination
Yishi Duan, Sheng Li
The space-time disclination is studied by making use of the decomposition theory of gauge potential in terms of antisymmetric tensor field and -mapping method. It is shown that…
