Boundary conditions, effective action, and Virasoro algebra for AdS₃
… of General Relativity for small excitations from asymptotic transformations and use it to study conformal symmetry in the boundary of AdS3. By requiring finiteness of the boundary effective action(s) for certain asymptotic transformations, we derive the well known Virasoro algebra and central …

Magnetic charges and phase space renormalization of gravity
… regarding the existence of infinite-dimensional asymptotic symmetries in higher even dimensional non-linear gravity. In the second part of this thesis, we study the dual charges of N = 1 supergravity in asymptotically flat spacetime. The action considered is the usual supergravity action with a …

Conformal Properties of Spacetime
… possible constructions of quantum gravity. In an asymptotically flat spacetime, this property, which we call the Penrose property, is satisfied if for any two endless timelike curves λ, ν in the same domain of outer dependence, there exists a future directed timelike curve from λ to ν. Penrose …
