Torsion, Chern-Simons Term and Diffeomorphism Invariance
In the approach of gravity Chern-Simons
modification has been considered here. It has been found that Chern-Simons
contribution to the bianchi identity has become cancelled from that of the
scalar field part. But "homogeneity and isotropy" consideration of present day
cosmology is a consequence of the "strong equivalence principle" and
vice-versa.Comment: 8 page
