Individual Five-Dimensional Witnesses in SInC

The Witness sector is taken to comprise individual five-dimensional entities; wavefunctions and densities describe those entities without constituting their ontology. This supplement selects one explicit massive-worldline completion and includes the distinct ECO gravitational car...

Hybrid Five-Dimensional Gravity with a Constrained Vector

We study a one-boundary five-dimensional Einstein–AdS construction coupled to one additional bulk carrier, a Maxwell field whose normalisable zero mode is subject to a unit-timelike constraint and nonlinear interaction on the observer boundary. The reduced boundary theory lies in...

Hybrid 5D Gravity (H5DG): A Step Towards Unification

This record contains the complete sixteen-paper corpus of Hybrid 5D Gravity (H5DG), assembled as a single ordered reference edition. H5DG investigates how far a single-boundary five-dimensional braneworld can provide a unified framework for gravitational phenomenology, from the S...

Hybrid 5D Gravity (H5DG): A Step Towards Unification

Hybrid 5D Gravity (H5DG) is a fourteen-paper theory of gravity and gravitational unification that investigates whether a deliberately constrained five-dimensional braneworld can connect relativistic gravity, galactic dynamics, gravitational lensing, a collisionless dark sector, p...
