Holography, Duality and Higher-Spin Theories
نویسنده
چکیده
I review recent work on the holographic relation between higher-spin theories in Anti-de Sitter spaces and conformal field theories. I present the main results of studies concerning the higher-spin holographic dual of the three-dimensional O(N) vector model. I discuss the special role played by certain double-trace deformations in Conformal Field Theories that have higher-spin holographic duals. Using the canonical formulation I show that duality transformations in a U(1) gauge theory on AdS4 induce boundary double-trace deformations. I argue that a similar effect takes place in the holography of linearized higher-spin theories on AdS4. Based on a lecture given at the First Solvay Workshop, “Higher-Spin Gauge Theories”, Brussels, May 12-14 2004. Notes taken by K. Alkalaev.

Holography and Emergent 4D Gravity
I review recent work toward constructing, via five-dimensional holographic duals, fourdimensional theories in which spin-2 states (gravitons) are emergent. The basic idea is to extend to gravity model-building the applications of holographic duality to phenomenology construction.
متن کاملThe Holographic Dual of a SUSY Vector Model and Tensionless Open Strings
We describe a supersymmetric example of the holographic duality between 3 dimensional vector models and higher spin gauge theories in AdS4, first proposed in a bosonic context by Klebanov and Polyakov. We argue that a particular Fradkin-Vasiliev type supersymmetric higher spin gauge theory in AdS4 with 16 supersymmetries is dual to the singlet sector of bilinear operators of a free N = 4, SU(N)...
متن کاملOn Locality, Holography and Unfolding
We study the functional class and locality problems in the context of higher-spin theories and Vasiliev’s equations. A locality criterion that is sufficient to make higher-spin theories well-defined as field theories on Anti-de-Sitter space is proposed. This criterion identifies admissible pseudo-local field redefinitions which preserve AdS/CFT correlation functions as we check in the 3d exampl...
متن کاملNoncommutative Sp(2,R) Gauge Theories A Field Theory Approach to Two-Time Physics
Phase-space and its relativistic extension is a natural space for realizing Sp(2,R) symmetry through canonical transformations. On a D×2 dimensional covariant phase-space, we formulate noncommutative field theories, where Sp(2,R) plays a role as either a global or a gauge symmetry group. In both cases these field theories have potential applications, including certain aspects of string theories...
متن کاملGeometric Metastability, Quivers and Holography
We use large N duality to study brane/anti-brane configurations on a class of CalabiYau manifolds. With only branes present, the Calabi-Yau manifolds in question give rise to N = 2 ADE quiver theories deformed by superpotential terms. We show that the large N duality conjecture of [1] reproduces correctly the known qualitative features of the brane/anti-brane physics. In the supersymmetric case...
