Query: Slowly expanding stable dust spacetimes   We establish the future nonlinear stability of a large class of FLRW models
as solutions to the Einstein-Dust system. We consider the case of a vanishing
cosmological constant, which in particular implies that the expansion rate of
the respective models is linear i.e. has zero acceleration. The resulting
spacetimes are future globally regular. These solutions constitute the first
generic class of future regular Einstein-Dust spacetimes not undergoing
accelerated expansion and are thereby the slowest expanding generic family of
future complete Einstein-Dust spacetimes currently known.
