The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

Effective field theories describing gravity coupled to matter are investigated, allowing for
operators of arbitrary mass dimension. Terms violating local Lorentz and diffeomorphism …

The Cauchy slicings for globally hyperbolic spacetimes and their relation with the causal
boundary are surveyed and revisited, starting at the seminal conformal boundary …

Many effective field theories describing gravity cannot arise from an underlying theory based
on Riemann geometry or its extensions to include torsion and nonmetricity but may instead …

In the attempts to apply Finsler geometry to construct an extension of general relativity, the
question about a suitable generalization of the Einstein equations is still under debate …

Planck scale modified dispersion relations are one way to capture the influence of quantum
gravity on the propagation of fundamental point particles effectively. We derive the time …

Expanding the work of Wall [Int. J. Mod. Phys. D 24, 1544014 (2015) IMPDEO 0218-2718
10.1142/S0218271815440149], we show that black holes obey a second law for linear …

In this work, we extend the study of Schwarzschi ld–Finsler–Randers (SFR) spacetime
previously investigated by a subset of the present authors (Triantafyllopoulos et al. in Eur …

This paper introduces a general mathematical framework for action-based field theories on
Finsler spacetimes. As most often fields on Finsler spacetime (eg, the Finsler fundamental …

In this work we investigate the anisotropic conformal structure of the gravitational field
incorporating dark gravity in a generalized Lagrange geometric framework on the Lorentz …
