Dirichlet boundary value problem for Chern-Simons modified gravity

arXiv:0803.1485 · doi:10.1103/PhysRevD.78.081502

Abstract

Chern-Simons modified gravity comprises the Einstein-Hilbert action and a higher-derivative interaction containing the Chern-Pontryagin density. We derive the analog of the Gibbons-Hawking-York boundary term required to render the Dirichlet boundary value problem well-defined. It turns out to be a boundary Chern-Simons action for the extrinsic curvature. We address applications to black hole thermodynamics.
