报告摘要：

By introducing the ruler field, AdS gravity is reformulated as a SO(2,d) gauge theory. In this formalism, the bulk Einstein equation can be naturally identified with the vanishing of boundary SO(2,d) covariant anomaly. Parallel with the results for chiral gauge anomaly, one can establish the descendent structure of this holographic SO(2,d) anomaly. The corresponding d+2 form anomaly characteristic can be viewed as a generalization of Euler class. To reproduce the holographic SO(2,d) anomaly in a pure CFT computation, the general SO(2,d) Dirac operators are constructed in the unfolding formalism of conformal primaries.  We also conjecture that holographic SO(2,d) anomaly is the topological obstruction for the quantum extension of classical SO(2,d) gauge symmetry.
