Extracting Edge Modes: Reduction of 3D and 2D Gravities
Euihun Joung, Sejin Kim
We investigate the boundary reduction of 3D Einstein gravity and JT gravity into their respective edge mode theories - namely, the Liouville and Alekseev-Shatashvili, and Schwarzia…

Higher-order chiral scalar from boundary reduction of 3d higher-spin gravity
Calvin Yi-Ren Chen, Euihun Joung, Karapet Mkrtchyan +1
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 f…
