(Anti)-de Sitter with leaky boundaries and corners
Robert McNees, Céline Zwikel
We construct charges for four-dimensional spacetimes with a non-vanishing cosmological constant, including charges that are not conserved because of a leaky boundary and charges as…

The symplectic potential for leaky boundaries
Robert McNees, Céline Zwikel
Charges associated with gauge symmetries are defined on boundaries of spacetimes. But these constructions typically involve divergent quantities when considering asymptotic boundar…
