-inextendibility of a class of Vaidya spacetimes
Karim Mosani, Clemens Sämann, Kharanshu N. Solanki
We prove the future -inextendibility of a broad subclass of ingoing Vaidya spacetimes with positive mass function satisfying the weak energy condition, building on methods int…
Doubling for chronological diamonds in Lorentzian geometry
Mauricio Che, Sebastian Gieger, Clemens Sämann
We define doubling conditions for measured Lorentzian length spaces in terms of chronological diamonds, and prove that such conditions are implied by suitable timelike curvature bo…
Stability of Synthetic Timelike Ricci Bounds under -Limits and Applications to Impulsive Gravitational Waves
Andrea Mondino, Vanessa Ryborz, Clemens Sämann
We investigate the stability of timelike Ricci curvature lower bounds under low-regularity limits of Lorentzian metrics. Specifically, we prove that the synthetic curvature-dimensi…
Curvature bounds, regularity and inextendibility of spacetimes
Tobias Beran, John Harvey, Clemens Sämann
We provide a completely new relation between curvature bounds and definiteness of the causal character of maximizers by exploiting the robust notion of synthetic curvature. This en…
