DOI: 10.1007/jhep07(2021)057
Abstract: Abstract In a region with a boundary, the gravitational phase space consists of radiative modes in the interior and edge modes at the boundary. Such edge modes are necessary to explain how the region couples… read more here.

DOI: 10.1007/s10714-020-02716-9
Abstract: In the literature different concepts of compatibility between a projective structure $${\mathscr {P}}$$ P and a conformal structure $${\mathscr {C}}$$ C on a differentiable manifold are used. In particular compatibility in the sense of Weyl… read more here.
