Abstract

We use a recently proposed covariant procedure to reduce the Chern-Simons action of three-dimensional higher-spin gravity to the boundary, resulting in a Lorentz covariant action for higher-order chiral scalars. After gauge-fixing, we obtain a higher-derivative action generalizing the s = 1 Floreanini-Jackiw and s = 2 Alekseev-Shatashvili actions to arbitrary spin s. For simplicity, we treat the case of general spin at the linearized level, while the full non-linear asymptotic boundary conditions are presented in component form for the SL(3, ℝ) case. Finally, we extend the spin-3 linearized analysis to a background with non-trivial higher-spin charge and show that it has a richer structure of zero modes.

三维高自旋引力边界约简的高阶手性标量

我们使用最近提出的协变过程将三维高自旋引力的chen - simons作用降至边界，从而得到高阶手性标量的Lorentz协变作用。在规范固定之后，我们得到了一个将s = 1 Floreanini-Jackiw和s = 2 Alekseev-Shatashvili作用推广到任意自旋s的高导数作用。为了简单起见，我们在线性化水平上处理一般自旋的情况，而对于SL（3,∈）情况，我们以分量形式给出了完整的非线性渐近边界条件。最后，我们将自旋-3线性化分析推广到具有非平凡高自旋电荷的背景下，并证明它具有更丰富的零模式结构。
