Ricci Symmetries of Static Space-Times with maximal Symmetric Transverse Spaces

引用

Communications in Theoretical Physics 2008年第5期49卷 1229-1234页

作者： m.akbar Centre for Advanced mathematics and Physics National University of Sciences and TechnologyPeshawar RoadRawalpindiPakistan

In the paper [m. akbar and R.G. Cai, Commun. Theor. Phys. 45 （2006） 95], a complete classification is provided with at least one component of the vector field V is zero. In this paper, I consider the vector field V with all non-zero components and the static space times with maximal symmetric transverse spaces are classified according to their Ricci collineations. These are investigated for non-degenerate Ricci tensor det R ≠0. It turns out that the only collineations admitted by these spaces can be ten, seven, six or four. It also covers our previous results as a spacial case. Some new metrics admitting proper Ricci collineations are also investigated.

The objective of this paper is to investigate the thermodynamic properties of mc Vittie universe. It turns out that the Einstein field equations are obtained by using Clausius equation near apparent horizon of mc Vittie *** the existence of horizons, different conditions in terms of mc Vittie parameters are discussed. Diverse cases of surface gravity are studied and conditions in terms of parameters for which surface gravity is positive, zero and negative are obtained and analyzed. It is shown that the generalized second law(GSL) holds near the apparent horizon if˙RA > *** results show that the heat capacity, CP, of the universe is always negative for matter dominated phase having P = 0. On the other hand, when P > 0, the heat capacity CP > 0 provided RA >√2/√8πP- 3H2 and negative otherwise. Furthermore, when P > 0, the temperature of the universe is minimum at Rmin =√2/√8πP- 3H2 while its heat capacity diverges.
