Abstract: We examine how the Einstein-Hilbert action is renormalized by adding the usual counterterms and additional corner counterterms when the boundary surface has corners. A bulk geometry asymptotic to H d +1 can have boundaries S… read more here.

DOI: 10.1016/j.geomphys.2019.04.012
Abstract: Abstract In this article we introduce A -valued Einstein–Hilbert–Palatini functional ( A -EHP) over a n -manifold M , where A is an arbitrary graded algebra, as a generalization of the functional arising in the… read more here.

DOI: 10.1142/s0217751x24501252
Abstract: Although with great successes in explaining phenomena and natural behaviour involving the Universe or a part thereof, the General Theory of Relativity is far from a complete theory. Focusing on its extension within the framework… read more here.
