Mach-Dicke conjecture on the coupling between spacetime and matter
In a scalar-tensor theory of gravity, spacetime is coupled to matter, and the distribution of mass in the Universe determines this coupling. Mach-Dicke conjecture. The coupling bet…

The most general multi-scalar-tensor theory in arbitrary dimensions and backgrounds
The multiple scalar field theory in flat space-time is obtained by requiring that its field equations have derivative order at most two. A covariantisation procedure extends this t…
