Abstract
A study of curvature collineations in conformally flat spacetimes is given. It is shown that the only possibilities are (special cases of the) FRW met rics land their spacelike equivalents), the Bertotti-Robinson metrics and n ull fluid metrics. The situation is completely resolved in the first two ca ses and also in the last case when this represents a null Einstein-Maxwell spacetime.
