Abstract
We show every toric Sasaki-Einstein manifold S admits a special Legendrian submanifold L which arises as the link fix(τ)∩ S of the fixed point set fix(τ) of an anti-holomorphic involution τ on the cone C(S). In particular, we obtain a special Legendrian torus S1× S1 in an irregular toric Sasaki-Einstein manifold which is diffeomorphic to S2× S3. Moreover, there exists a special Legendrian submanifold in ♯m(S2× S3) for each m≧1.
