Conformal Vacuum of dS${}_4\times \mathbb{R}$ with Oppositely Oriented Boundaries

Lucas K. Kovalsky, Shivesh Pathak, Kyle Ritchie

We derive a dS${}_4\times \mathbb{R}$ quotient spacetime that is asymptotically dS${}_4$, where the quotient makes its past boundary oppositely oriented relative to its future boundary…
