Description (deu)
This talk was part of the Workshop on "Mathematical Relativity: Past, Present, Future" held at the ESI December 4 — 7, 2023.
We discuss forthcoming work establishing the C^0-inextendibility of FLRW spacetimes without particle horizons in the case of positive spatial sectional curvature and, with some additional assumptions on the scale factor, in the case of negative spatial sectional curvature.
