An Einstein structure is a  Riemannian metric on a manifold M such that $Ric=k g$   for  a  constant  $k$. $Ric$ is the Ricci tensor and $g$ is the metric tensor

Are  there  any relations between existence of  an  Einstein structure on a Lie  group  and  chirality of its  Lie  algebra? Under  what  conditions  a Lie  group whose  Lie  algebra is  a  chiral algebra admit an Einstein structure?

What is an Einstein structure? Please give a reference.
