Non-primary square roots in massive gravity
Alexey Golovnev
Non-linear dRGT massive and bimetric gravities are complicated theories constructed in terms of square roots of matrices. Apart from the technical issues of successfully working wi…
Vector modes in Type 3 New GR
Alexey Golovnev
Some time ago, we published the full count of degrees of freedom in the linearised weak gravity limit of arbitrary New GR models. We did it by considering the linear weak gravity e…
Revisiting the relaxation of constraints in gauge theories
Alexey Golovnev, Kirill Russkov
Recently, there were works claiming that path integral quantisation of gauge theories necessarily requires relaxation of Lagrangian constraints. As has also been noted in the liter…
Is there any Trinity of Gravity, to start with?
Alexey Golovnev
In recent years, it has been rather fashionable to talk about geometric trinity of gravity. The main idea is that one can formally present the gravity equations in different terms,…
Degrees of Freedom in modified Teleparallel Gravity
Alexey Golovnev
I discuss the issue of degrees of freedom in modified teleparallel gravity. These theories do have an extra structure on top of the usual (pseudo)Riemannian manifold, that of a fla…
Geometry of teleparallel theories
Alexey Golovnev
I give a brief introduction to and explain the geometry of teleparallel models of modified gravity. In particular I explain why, in my opinion, the covariantised approaches are not…
