Asymptotic Symmetry Algebras in Non-Anti-de-Sitter Higher-Spin Gauge
Theories    [PDF]

Max Riegler

We analyze asymptotic symmetry algebras in (2+1)-dimensional non-AdS higher-spin gravity with a focus on AdS$_2\times\mathbb{R}$ and $\mathbb{H}_2\times\mathbb{R}$. We find a consistent set of boundary conditions for spin-3 gravity in the non-principal embedding and calculate the corresponding asymptotic symmetry algebra in the classical and quantum mechanical case. In addition, we check for unitary representations of the resulting quantum $\mathcal{W}_3^{(2)}$ algebra and give an interpretation of the corresponding CFT.
