# The relation between conformally related metrics and conformal vector fields?

Two metrics $g_{1}$ and $g_{2}$ are conformally equivalent metrics if $g_{2}=e^{2\theta}g_{1}$ A vector field $X$ is called conformal if $L_{X}g=2\theta g$ where $L_{X}$ is the Lie derivative with respect to $X$.

Is there a relation between both concepts?

Yes, and you answered this question elsewhere: the flow of a conformal vector field is a family of conformal maps. That is, pulling back $g$ under a flow map gives you a conformally equivalent metric. –  Post No Bulls Dec 25 '13 at 7:47
