The Topological Structure of Nieh-Yan Form and Chiral Anomaly in Spaces with Torsion
Sheng Li
The topological structure of the Nieh-Yan form in 4-dimensional manifold is given by making use of the decomposition of spin connection. The case of the generalized Nieh-Yan form o…

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…

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…
