Timelike Ricci curvature lower bounds via optimal transport for Orlicz-type Lorentzian costs
Argam Ohanyan, Marta Sálamo Candal
We study the optimal transport problem on globally hyperbolic spacetimes associated with Orlicz-type Lorentzian cost functions of the form , where is a suitable m…

Comparison theory for Lipschitz spacetimes
Mathias Braun, Marta Sálamo Candal
We prove a globally hyperbolic spacetime with locally Lipschitz continuous metric and timelike distributional Ricci curvature bounded from below obeys the timelike measure contract…
