Timelike Ricci bounds for low regularity spacetimes by optimal transport

Mathias Braun, Matteo Calisti

We prove that a globally hyperbolic smooth spacetime endowed with a $C^{1}$ -Lorentzian metric whose Ricci tensor is bounded from below in all timelike directions, in…

Rényi's entropy on Lorentzian spaces. Timelike curvature-dimension conditions

Mathias Braun

For a Lorentzian space measured by $m$ in the sense of Kunzinger, Sämann, Cavalletti, and Mondino, we introduce and study synthetic notions of timelike lower Ricci curva…

Good geodesics satisfying the timelike curvature-dimension condition

Mathias Braun

Let $(M, d, m, ≪, \leq, τ)$ be a causally closed, $K$ -globally hyperbolic, regular measured Lorentzian geodesic space satisfying the weak timelike curvat…
