AdS/CFT Correspondence And Topological Field Theory
نویسنده
چکیده
In N = 4 super Yang-Mills theory on a four-manifold M , one can specify a discrete magnetic flux valued in H 2 (M, Z N). This flux is encoded in the AdS/CFT correspondence in terms of a five-dimensional topological field theory with Chern-Simons action. A similar topological field theory in seven dimensions governs the space of " conformal blocks " of the six-dimensional (0, 2) conformal field theory.

We study duality of field theories in (d+1) dimensional flat Euclidean space and (d+1) dimensional Euclidean AdS space for both scalar the and vector fields. In the case of the scalar theory, the injective map between conformally coupled massless scalars in two spaces is reviewed. It is shown that for vector fields the injective map exists only in four dimensions. Since Euclidean AdS space is e...
متن کاملTopological Ward Identity and Anti-de Sitter Space/CFT Correspondence
The dual relationship between the supergravity in the anti-de Sitter(AdS) space and the superconformal field theory is discussed in the simplest form We show that a topological Ward identity holds in the three dimensional Chern-Simons gravity. In this simple case the proposed dual relationship can be understood as the topological Ward identity. Extensions to the supersymmetric theories and high...

In a recent paper Klebanov and Witten [4] proposed to fomulate the AdS/CFT correspondence principle by imposing an " irregular boundary condition " for a scalar field. In this paper we generalize this idea to the case of spinor field with interaction. The action functional following from the choice of irregular boundary conditions and which must be used in the AdS/CFT correspondence is related ...

The prescription of the AdS/CFT correspondence is refined by using a regularization procedure, which makes it possible to calculate the divergent local terms in the CFT two-point function. We present the procedure for the example of the scalar field. It has been stated in most papers on this subject that the correspondence between a fields theory on anti-de Sitter space (AdS) and a conformal fi...
متن کاملA Very Introductory AdS/CFT
The AdS/CFT correspondence, conjectured by Maldecena in late 1997, has been playing an essential role in modern string theory. The original version of this gravity/gauge AdS/CFT correspondence states an equivalence between Type 2B string theory on AdS5 × S and N = 4 super Yang-Mills theory in 4D, under certain parameter region. Namely, for these two theories, the operator variables, physical st...
