Variations of Gauss-Codazzi-Ricci Equations in Kaluza-Klein Reduction (String Theory) and Cauchy Problem (General Relativity)
Pei Wang
We find a kind of variations of Gauss-Codazzi-Ricci equations suitable for Kaluza-Klein reduction and Cauchy problem. Especially the counterpart of extrinsic curvature tensor has a…
Morita Equivalence and Interpolation of The Dirac-Born-infeld Theory on the Non-Commutative Torus
Pei Wang, Rui-Hong Yue, Kang-Jie Shi
In the noncommutative Dirac-Born-Infeld action with Chern-Simons term, an interpolation field is used in both DBI action and Chern-Simons term. The Morita equivalence is discus…
W-symmetries on the Homogeneous Space G/U(1)^r
Xiang-Mao Ding, Pei Wang
A construction of -symmetries is given only in terms of the nonlocal fields (parafermions ${\ps}_{\al}$), which take values on the homogeneous space , where is a s…
Rotation of D-brane and Non-commutative Geometry
Pei Wang, Ruihong Yue
Our motivation is to find the relationship between the commutator of coordinates and uncertainty relation involving only the coordinates. The boundary condition with constant backg…
Nonelectromagnetic duality in twisted N=4 model
Pei Wang, Liu Zhao
In this paper we discuss the possible existing correlation functions in the N=4 topological model. Due to the distinguished feature that no anomaly exists in N=4 supersymmetric the…
