Asymptotically Non-Static Kerr-deSitter Spacetime With No Event Horizon
We present our derivations for Kerr-deSitter metric in a proper comoving
coordinate system.It asymptotically approaches to the deSitter metric in
Robertson-walker form.This has been done by considring the stationary
axially-symmetric spacetime in which motion of particle is integrable.That is
the Hamilton-Jacobi and Klein-Gordon equations are separable.In this form it is
asymptotically consistent with comoving frame.Comment: Title changed,revised arguments,results unchanged
Non-Static Spherically Symmetric solution of Einstein vacuum Field Equations with
The Schwarzschild-deSitter metric is the known solution of Einstein field
equations with cosmological constant term for vacuum spherically symmetric
space around a point mass M. Recently it has been reported that in a
-dominant world the Schwarzschild type coordinate systems are
disqualified by redshift-magnitude test as a proper frame of
reference(gr-qc/9812092). We derive the solution in a FRW type coordinate
system which is qualified according to the mentioned test. Asymptotically it
approachs to the non-static form of deSitter metric. The obtained metric is
transformable to Schwarzschild-deSitter metric. It is an analytic function of
for all values except which is singular. This is carried out with no
making use of Eddington-Finkelstein coordinates and without entering any cross
term in the metric.Comment: 9pages,no figures, Late
