I. Yavuz et I. Yilmaz, INHERITING CONFORMAL AND SPECIAL CONFORMAL KILLING VECTORS IN STRING COSMOLOGY, General relativity and gravitation, 29(10), 1997, pp. 1295-1307
In this paper we study the consequences of the existence of conformal
and special conformal Killing vectors (CKV, SCKV) for string cloud and
string fluid in the context of general relativity. The inheritance sy
mmetries of the string cloud and string fluid are discussed. Einstein'
s field equations have been solved for static spherically symmetric sp
ace-time with cloud and fluid of strings source via CKV.
