A Note on Friedman Universe with a Higher Order Gravity

A. M. Mishra

Abstract


New images of black-holes in recent times created a strong validity
of Friedman universe. Since Friedman universe possess singularity, synonymously
black holes, its quantum aspect becomes more important for
study. We have seen Friedman universe with reference to higher order
gravity theory, a natural generalization of Einstein theory of gravity. Particle
creation in vacuum space-time in presence of strong gravitation field
has explained and thus emphasised upon gravitons creation as well as
non-conformal invariance of higher order theory in this context.


Keywords
