A first-order formulation of f(R) gravity in spherical symmetry

gr-qc · 2025-12-07 · unverdicted · novelty 7.0

A first-order nonlocal integro-differential system for the scalar field phi and curvature R is derived for f(R) gravity in spherical symmetry, extending Christodoulou's approach to allow analysis of solutions via hyperbolic equations.
