We study the cosmic expansion history of massive bigravity with a viable matter coupling
which treats both metrics on equal footing. We derive the Friedmann equation for the …

A bstract We present a method of contraction that can be applied to re-construct the recent
extended non-relativistic and ultra-relativistic algebras as well as corresponding action …

Nonminimal matter couplings have recently been considered in the context of massive
gravity and multigravity. These couplings are free of the Boulware-Deser ghost in the …

We show that minimal massive 3 d gravity (MMG) of (Bergshoeff et al. in Class Quantum
Grav 31: 145008, 2014), as well as the topological massive gravity, are particular cases of a …

We reconsider the possibility of a class of new kinetic terms in the first order (vielbein)
formulation of massive gravity and multi-gravity. We find that new degrees of freedom …

We introduce a systematic way of constructing 3D exotic massive gravity theories in the first
order formulation. Our method is based on truncating a single degree of freedom in the …

A bstract In this paper we study multi-gravity (multi-metric and multi-vielbein) theories in the
presence of cycles of interactions (cycles in the so-called 'theory graph'). It has been …

A variant of the ADT method for the determination of gravitational charges as integrals at
infinity is applied to'Chern–Simons-like'theories of 3D gravity, and the result is used to find …

A bstract The existence of a ghost free theory of massive gravity begs for an interpre-tation
as a Higgs phase of General Relativity. We revisit the study of massive gravity as a Higgs …

A bstract We reconsider warped black hole solutions in topologically massive gravity and
find novel boundary conditions that allow for soft hairy excitations on the horizon. To …
