CLASSICAL AND QUANTUM GRAVITY
Abstract:
A physical and geometrical interpretation of previously introduced tensor operator algebras of U (2, 2) in terms of algebras of higher-conformal-spin quantum fields on the anti-de Sitter space AdS(5) is provided. These are higher-dimensional W-like algebras and constitute a potential gauge guide principle towards the formulation of induced conformal gravities (Wess-Zumino-Witten-like models) in realistic dimensions. Some remarks on quantum (Moyal) deformations are given and potentially tractable versions of non-commutative AdS spaces are also sketched. The role of conformal symmetry in the microscopic description of Unruh and Hawking's radiation effects is discussed.
