We construct a conformal supergravity using the AdS/CFT correspondence. We derive the five dimensional conformal supergravity which plays the role of sources for the operators in five dimensionalâ€¦ (More)

Anomalies of N = (4, 4) superconformal field theories coupled to a conformal supergravity background in two dimensions are computed by using the AdS/CFT correspondence. We find that Weyl, axial gaugeâ€¦ (More)

We study how local symmetry transformations of (p, q) anti de Sitter supergravities in three dimensions act on fields on the two-dimensional boundary. The boundary transformation laws are shown to beâ€¦ (More)

It is shown that local symmetry transformations of the maximal AdS supergravity in seven-dimensional anti de Sitter space induce those of the N = (2, 0) conformal supergravity on the six-dimensionalâ€¦ (More)

We find solutions of the six-dimensional maximal supergravity by adding a perturbation of vector fields to the solution AdS3 Ã— S3. For certain perturbations the solution represents a dual descriptionâ€¦ (More)

We consider the open string tachyon action in a worldâ€“sheet sigma model approach. We present explicit calculations up to order 8 in derivatives for the bosonic string, and mimic these to order 6 forâ€¦ (More)

We discuss the chiral symmetry breaking in general intersecting Dq/Dp brane models consisting of Nc Dq-branes and a single Dp-brane with an s-dimensional intersection. There exists a QCD-like theoryâ€¦ (More)

Symmetry breaking by perturbations in the AdS/CFT correspondence is discussed. Perturbations of vector fields to the AdS3 Ã— S solution of the six-dimensional N = (4, 4) supergravity are considered.â€¦ (More)
