$C^{0}$ -inextendibility of a class of warped-product black hole spacetimes

Karim Mosani

We adapt Sbierski's proof of $C^{0}$ -inextendibility of the maximal analytic Schwarzschild spacetime to a broad class of warped-product black hole spacetimes with a static exterior r…

Conformal transformations of metric spaces and Lorentzian pre-length spaces

Miguel Manzano, Karim Mosani, Clemens Sämann +1

We introduce conformal transformations in the synthetic setting of metric spaces and Lorentzian (pre-)length spaces. Our main focus lies on the Lorentzian case, where, motivated by…
