Sasakian manifolds are odd dimensional analog of Kahler manifolds,

and it is an interesting question to determine when

a Sasakian manifold admits an Einstein metric. Five dimensional

Sasaki-Einstein (SE) manifolds play an important role in AdS/CFT

correspondence, which relates a string theory and a quantum field theory. I

will discuss the existence of SE manifolds and its geometric properties

which will be of great interest to AdS/CFT correspondence.
