Torsion and Nonmetricity in Scalar-Tensor Theories of Gravity
Jean-paul Berthias, Bahman Shahid-Saless
Abstract
We show that the gravitational field equations derived from an action composed of i) an arbitrary function of the scalar curvature and other scalar fields plus ii) connection-independent kinetic and source terms, are identical whether one chooses nonmetricity to vanish and have non-zero torsion or vice versa.
