A New Infinite Class of Sasaki-Einstein Manifolds
نویسندگان
چکیده
We show that for every positive curvature Kähler–Einstein manifold in dimension 2n there is a countably infinite class of associated Sasaki– Einstein manifolds X2n+3 in dimension 2n + 3. When n = 1 we recover a recently discovered family of supersymmetric AdS5 × X5 solutions of type IIB string theory, while when n = 2 we obtain new supersymmetric AdS4×X7 solutions of D = 11 supergravity. Both are expected to provide new supergravity duals of superconformal field theories. ∗ On leave from: Blackett Laboratory, Imperial College, London, SW7 2BZ, U.K.

Warped product and quasi-Einstein metrics
Warped products provide a rich class of physically significant geometric objects. Warped product construction is an important method to produce a new metric with a base manifold and a fibre. We construct compact base manifolds with a positive scalar curvature which do not admit any non-trivial quasi-Einstein warped product, and non compact complete base manifolds which do not admit any non-triv...
متن کاملA New Infinite Class of Supersymmetric AdS3 Solutions
Explict examples of the AdS/CFT correspondence, where detailed calculations can be performed, are very useful in developing our understanding of the correspondence. A good example is the discovery of an infinite class of Sasaki-Einstein manifolds in [1, 2], each of which gives rise to a supersymmetric solution of type IIB string theory with an AdS5 factor. This discovery combined with the subse...
متن کاملToric Geometry, Sasaki–Einstein Manifolds and a New Infinite Class of AdS/CFT Duals
Recently an infinite family of explicit Sasaki–Einstein metrics Y p,q on S2 × S3 has been discovered, where p and q are two coprime positive integers, with q < p. These give rise to a corresponding family of Calabi–Yau cones, which moreover are toric. Aided by several recent results in toric geometry, we show that these are Kähler quotients C4//U(1), namely the vacua of gauged linear sigma mode...
متن کاملNew Einstein-Sasaki spaces in five and higher dimensions.
We obtain infinite classes of new Einstein-Sasaki metrics on complete and nonsingular manifolds. They arise, after Euclideanization, from BPS limits of the rotating Kerr-de Sitter black hole metrics. The new Einstein-Sasaki spaces L(p,q,r) in five dimensions have cohomogeneity 2 and U(1) x U(1) x U(1) isometry group. They are topologically S(2) x S(3). Their AdS/CFT duals describe quiver theori...
متن کاملTransverse Kähler Geometry of Sasaki Manifolds and Toric Sasaki-einstein Manifolds
In this paper we study compact Sasaki manifolds in view of transverse Kähler geometry and extend some results in Kähler geometry to Sasaki manifolds. In particular we define integral invariants which obstruct the existence of transverse Kähler metric with harmonic Chern forms. The integral invariant f1 for the first Chern class case becomes an obstruction to the existence of transverse Kähler m...
