三维高自旋规范理论中的渐近W对称性

Asymptotic W-symmetries in three-dimensional higher-spin gauge theories

Andrea Campoleoni, Stefan Fredenhagen, Stefan Pfenninger

摘要:

本文讨论了在渐近AdS背景下,如何系统地计算一般三维玻色子高自旋规范理论的渐近对称代数。我们将这些技巧应用于单参数的高自旋规范理论族,这些规范理论可以被认为是SL(N)× SL(N)Chern-Simons理论的大N极限,并且我们提供了一个关于所得到的无限维非线性W-代数的结构常数的封闭公式。在此基础上,我们给出了所有经典W_N代数的结构常数的封闭公式。在这两个例子中,W-代数的高自旋生成元都是Virasoro主元。我们最终将讨论如何将我们的基础与以前在文献中讨论过的非初等二次基联系起来。

英文摘要:

We discuss how to systematically compute the asymptotic symmetry algebras of generic three-dimensional bosonic higher-spin gauge theories in backgrounds that are asymptotically AdS. We apply these techniques to a one-parameter family of higher-spin gauge theories that can be considered as large N limits of SL(N) x SL(N) Chern-Simons theories, and we provide a closed formula for the structure constants of the resulting infinite-dimensional non-linear W-algebras. Along the way we provide a closed formula for the structure constants of all classical W_N algebras. In both examples the higher-spin generators of the W-algebras are Virasoro primaries. We eventually discuss how to relate our basis to a non-primary quadratic basis that was previously discussed in literature.
