On the functional determinant of a special operator with a zero mode in cosmology
functional determinant special operator
2011/3/2
The functional determinant of a special second order quantum-mechanical operator is calcu-lated with its zero mode gauged out by the method of the Faddeev-Popov gauge fixing procedure.
The coupling of topology and inflation in Noncommutative Cosmology
coupling of topology inflation Noncommutative Cosmology
2011/3/2
We show that, in a model of modi ed gravity based on the spectral action functional, there is a nontrivial coupling between cosmic topology and in ation, in the sense that the shape of the possible sl...
LRS Bianchi Type -V Cosmology with Heat Flow in Scalar -Tensor Theory
Cosmology Bianchi type models Hubble parameter Deceleration parameter Inflationary model Heat flow
2010/7/8
In this paper we present a spatially homogeneous locally rotationally symmetric (LRS) Bianchi type -V perfect fluid model with heat conduction in scalar tensor theory proposed by Saez and Ballester. T...
