A note on the total action of 4D Gauss–Bonnet theory
Abstract Recently, a novel four-dimensional Gauss–Bonnet theory has been suggested as a limiting case of the original D-dimensional theory with singular Gauss–Bonnet coupling constant $$\alpha \rightarrow \alpha /(D-4)$$ α → α / ( D - 4 ) . The theory is proposed at the level of field equations. Her...
