On Beltrami Model of de Sitter Spacetime
Han-Ying Guo, Chao-Guang Huang, Zhan Xu +1
Based on some important properties of space, we present a Beltrami model that may shed light on the observable puzzle of space and the paradox between the sp…
(Super)gravity and Yang-Mills Theories as Generalized Topological Fields with Constraints
Yi Ling, Roh-Suan Tung, Han-Ying Guo
We present a general approach to construct a class of generalized topological field theories with constraints by means of generalized differential calculus and its application to c…
The Euler-Lagrange Cohomology Groups on Symplectic Manifolds
Han-Ying Guo, Jianzhong Pan, Ke Wu +1
The definition and properties of the Euler-Lagrange cohomology groups , , on a symplectic manifold are given and studied. F…
On Diffeomorphism Invariance and Black Hole Entropy
Chao-Guang Huang, Han-Ying Guo, Xiaoning Wu
The Noether-charge realization and the Hamiltonian realization for the $\diff({\cal M})$ algebra in diffeomorphism invariant gravitational theories are studied in a covariant forma…
The Euler-Lagrange Cohomology and General Volume-Preserving Systems
Bin Zhou, Han-Ying Guo, Jianzhong Pan +1
We briefly introduce the conception on Euler-Lagrange cohomology groups on a symplectic manifold and systematically present the general form of volume-prese…
