Gravitational corner conditions in holography by Gary T. Horowitz, Diandian Wang

“…Abstract Contrary to popular belief, asymptotically anti-de Sitter solutions of gravitational theories cannot be obtained by taking initial data (satisfying the constraints) on a spacelike surface, and choosing an arbitrary conformal metric on the timelike boundary at infinity. …”

Queering the City: Understanding Gravitational Forces by Petra L. Doan

“…The strategic aim of these comparisons is to expand our understanding of queer spaces and to elaborate a more fluid model of queering cities. The paper uses a gravitational framework that identifies the centering (centripetal) and decentering (centrifugal) forces and the interplay between these forces. …”
