Cosmology of fractional gravity

Ivan Salvador-Garcia, Gianluca Calcagni ยท 2026

This is a first study of the cosmology of classical fractional gravity, a nonlocal proposal endowed with self-adjoint fractional d'Alembertian operators which serves as the basis for an ultraviolet-coโ€ฆ

The Hawking Singularity Theorem for H\"older Continuous Metrics with $L^p$-Bounded Curvature

Michael Kunzinger, Moritz Reintjes, Roland Steinbauer, Ines Vega-Gonzalez ยท 2026

We prove a low-regularity version of Hawking's singularity theorem for Lorentzian metrics in $W^{1,p}$ with Riemann curvature in $L^p$, where $p>2n$ and $n$ the dimension of spacetime. This extends prโ€ฆ
