VACUUM POLARIZATION ENERGYMOMENTUM TENSORS FOR SCALAR FIELD IN CURVED SPACETIME

The general expression of vacuum polarization energymomentum tensors for scalar field is derived in one loop approximation. Some special cases are discussed. Parts of the energymomentum tensors for scalar field around the Kerr-Newman blackholes are calculated.

EVENT HORIZON AND HAWKING RADIATION

The Hawking radiation of charged Dirac particles in Kerr-Newmande Sitter (KNdS) space-time is studied in spinor formalism in this letter.
