Rigidity theorem for the Borell-Brascamp-Lieb inequality is shown on weighted Riemannian manifolds, generalizing Balogh-Kristály to the weighted setting.
An analogue of Reshetnyak's majorisation theorem is proven for Lorentzian length spaces with upper curvature bounds, yielding a four-point characterization of those bounds suitable for discrete settings.
Introduces a synthetic null energy condition using optimal transport on topological causal spaces that agrees with the classical NEC in smooth cases and enables proofs of area and singularity theorems in non-smooth settings.
Under the strong energy condition, positive lower bounds on asymptotic volume-expansion invariants imply past timelike geodesic incompleteness with explicit time bound; extends to synthetic TCD^e_p(0,N) length spaces.
Introduces locally uniformly d-controlling maps preserving causal diamond diameters and proves the coarea inequality for Lorentzian Hausdorff measure in pre-length spaces, plus a covering lemma under local causal enlargement.
