Correspondence to Schwarzschild solution

In the static case, we have established the relation between coordinate and conformal scalar field , while this conformal scalar does not vary with coordinate, satisfying the static condition . We must take note however that the form of this conformal scalar as a function depends on an auxiliary scalar field through a form of compactification we have defined by (4). Later we shall find that the form of this auxiliary scalar is not fixed (no form that is a unique solution) although subject to an identity equation that will result from the equation of motion of the conformal scalar.

To establish correspondence to Schwarzschild solution we first write

(21.1)

This has resulted following (20.13), given (20.14) and (20.15).

The form of our auxiliary field that can lead to the desired correspondence is given by hand and this takes the following form

(21.2)

Thus, our conformal scalar simply becomes the square of the radius of our two-sphere (3).

(21.3)

As a consequence we write the fundamental line element (2) on in the following given form

(21.4)

where

(21.5)

upon the normalization thus, fully establishing the correspondence to the Schwarzschild solution.
