Abstract
We develop a technique relating scalar fields with different masses in different conformally flat space-times. We apply this technique to the case of FRW space-times, with , and discuss several examples. We also study various energy conditions and discuss how they constrain the space-times related by this technique. In addition, we use this technique to study correlators for the related space-times in an example.
