Dirac-Lu Space with Pseudo-Riemannian Metric of Constant Curvature
《Acta Mathematica Sinica,English Series》2011年第9期1743-1752,共10页Xin An REN Li CHEN Gui Dong WANG 
In this paper, we will discuss the geometries of the Dirac-Lu space whose boundary is the third conformal space Af defined by Dirac and Lu. We firstly give the S0(3, 3) invariant pseudo- Riemannian metric with const...

Stability problem in Rindler spacetime
《Chinese Physics B》2007年第10期2889-2893,共5页田贵花 王世坤 钟树泉 
Project supported by the National Natural Science Foundation of China (Grant Nos 10475013, 10375087 and 10373003), the National Basic Research Program (Grant No 2004CB318000) and National Science Foundation for Post-Doctoral Scientists of China.
The stability problem of the Rindler spacetime is carefully studies by using the scalar wave perturbation. Using two different coordinate systems, the scalar wave equation is investigated. The results are different in...

“舟行不觉”和暗宇宙——惯性运动、相对性原理及其宇宙起源被引量:3
《科学文化评论》2006年第5期77-93,共17页郭汉英

在牛顿力学和狭义相对论中,惯性原理是定义物理量、引进物理规律的基准;然而,惯性运动和惯性系的起源没有解决,在如何确定惯性系的问题上,存在爱因斯坦所指出的“循环论证”。爱因斯坦试图引进任意运动之间的“广义相对性”摆脱惯性原...

Restudy of the stability problem of the Schwarzschild black hole
《Chinese Physics B》2006年第7期1430-1434,共5页田贵花 王世坤 赵峥 
Project supported by the National Natural Science Foundation of China (Grant Nos 10475013, 10373003 and 10375087), the National Basic Research Program (Grant No 2004CB318000) and the Post-Doctor Foundation of China.
The stability of the Schwarzschild black hole is restudied in the Painlevé coordinates. Using the Painlevé time coordinate to define the initial time, we reconsider the odd perturbation and find that the Schwarzschi...

带有背景矢量场的标量场暗能量模型(英文)
《高能物理与核物理》2006年第6期522-525,共4页李彦恒 
国家自然科学基金(90403023,10375087)资助~~
讨论了带有背景矢量场的动力学标量场作为暗能量在闭宇宙的情形下的演化.选取适当的标量场势函数后,在得到的暗能量有效状态方程中,参数ω在红移z≈0.2处可以越过-1,而且在z≈1.7处宇宙从减速膨胀的状态转变为加速膨胀状态,这与最近...
