摘要 |
Vasiliev's higher-spin theory is a generalization of Einstein's gravity theory. The diffeomorphism is extended to include higher-spin gauge symmetries, which soften the UV divergence of ordinary quantum gravity. The holographic dual of a higher-spin theory in AdS is a CFT with higher-spin currents. This holography is a weak/weak duality, and is related to a tensionless limit of string theory.
In the first part of talk I will review higher spin theory and its holographic duals. In the second part I discuss three topics in three-dimensions: modular behavior, 1/N correction, and higher-spin theory in higher-genus handle-bodies. |
