Title: SEMI-CLASSICAL GRAVITATIONAL EFFECTS AROUND GLOBAL MONOPOLES IN LYRA GEOMETRY.
Authors: Rahaman, Farook
Abstract: W.A. Hiscock (1990, Class. Quantum Gravitation 7, L235) obtained the vacuum expectation value of the stress-energy tensor of an arbitrary collection of conformal massless free quantum fields (scalar, spinor and vectors) in the space-time of a static global monopole. With this stress-energy tensor, the semi-classical Einstein equations are solved retaining terms up to first order in h in Lyra geometry.
