[期刊论文] 作者:WU Ya-Bo,LI Jiu-Li, 来源:中国物理快报(英文版) 年份:2001
The generalized two-parametric Hilbert-Palatini action is constructed, which not only includes the well-known Hilbert-Palatini and Ashtekar gravitational theory...
[期刊论文] 作者:Wu Ya-Bo(吴亚波),Li Lei(李磊), 来源:中国物理(英文版) 年份:2002
We establish the double complex Ashtekar gravitational theory with the cosmological term. In particular, by performing the 3+1 decomposition of the double Ashte...
