Vacuum cosmological spacetimes without CMC Cauchy surfaces
Vacuum cosmological spacetimes without CMC Cauchy surfaces
In this article, we extend a construction of [6] to obtain a large class of vacuum cosmological spacetimes that do not contain any CMC Cauchy surfaces. The allowed spatial topologies for these examples are of the form $M \# M$, where $M$ is any closed, oriented, irreducible $3$-manifold which is …
