The 3-string vertex and the AdS/CFT duality in the PP-wave limit
Paolo Di Vecchia, Jens Lyng Petersen, Michela Petrini +2
We pursue the study of string interactions in the PP-wave background and show that the proposal of hep-th/0211188 can be extended to a full supersymmetric vertex. Then we compute s…

Supergravity and the Knitting of the Kalb--Ramond Two-Form in Eight-Dimensional Topological Gravity
Laurent Baulieu, Marc Bellon, Alessandro Tanzini
Topological euclidean gravity is built in eight dimensions for manifolds with holonomy. In a previous work, we considered the construction of an eight-dimen…
