The formalism of invariants in scalar-tensor and multiscalar-tensor theories of gravitation
Laur Jarv, Piret Kuusk, Margus Saal +1
We give a brief summary of the formalism of invariants in general scalar-tensor and multiscalar-tensor gravities without derivative couplings. By rescaling of the metric and repara…
General relativity as an attractor for scalar-torsion cosmology
Laur Jarv, Alexey Toporensky
We study flat Friedmann-Lemaitre-Robertson-Walker cosmological models for a scalar field coupled nonminimally to teleparallel gravity with generic coupling and potential functions.…
Invariant quantities in the multiscalar-tensor theories of gravitation
Piret Kuusk, Laur Jarv, Ott Vilson
The aim of the current paper is to study the multiscalar-tensor theories of gravity without derivative couplings. We construct a few basic objects that are invariant under a Weyl r…
Transformation properties and general relativity regime in scalar-tensor theories
Laur Jarv, Piret Kuusk, Margus Saal +1
We consider first generation scalar-tensor theories of gravitation in a completely generic form, keeping the transformation functions of the local rescaling of the metric and the s…
Parametrizations in scalar-tensor theories of gravity and the limit of general relativity
Laur Jarv, Piret Kuusk, Margus Saal +1
We consider a general scalar-tensor theory of gravity and review briefly different forms it can be presented (different conformal frames and scalar field parametrizations). We inve…
