Strong cosmic censorship near Kerr in Christodoulou's square-integrable-connection formulation

For each fixed M>0M>0, 0<∣a∣<M0<|\mathfrak a|<M there is ε>0\varepsilon>0 such that, among smooth complete two-ended vacuum data dd with tenth weighted seminorm p10(d−d∗)<εp_{10}(d-d_*)<\varepsilon from the Kerr bridge data, those whose full maximal globally hyperbolic development has a future extension with continuous nondegenerate metric in Wloc1,2W^{1,2}_{\mathrm{loc}} form a meagre set in the weighted smooth topology. No symmetry is imposed and extensions need not be vacuum. Companions prove the weaker C2C^2 and C1C^1 versions. This is strong cosmic censorship in Christodoulou's formulation near Kerr only; it is not the global conjecture, and it does not treat one-ended or nonrotating data.
