Minimal Massive 3D Gravity Unitarity Redux
Alex S. Arvanitakis, Paul K. Townsend
A geometrical analysis of the bulk and anti-de Sitter boundary unitarity conditions of 3D "Minimal Massive Gravity" (MMG) (which evades the "bulk/boundary clash" of Topologically M…
Matter coupling in 3D "Minimal Massive Gravity"
Alex S. Arvanitakis, Alasdair J. Routh, Paul K. Townsend
The "Minimal Massive Gravity" (MMG) model of massive gravity in three spacetime dimensions (which has the same anti-de Sitter (AdS) bulk properties as "Topologically Massive Gravit…
Minimal Massive 3D Gravity
Eric Bergshoeff, Olaf Hohm, Wout Merbis +2
We present an alternative to Topologically Massive Gravity (TMG) with the same "minimal" bulk properties; i.e. a single local degree of freedom that is realized as a massive gravit…
Chern-Simons-like Gravity Theories
Eric A. Bergshoeff, Olaf Hohm, Wout Merbis +2
A wide class of three-dimensional gravity models can be put into "Chern-Simons-like" form. We perform a Hamiltonian analysis of the general model and then specialise to Einstein-Ca…
All Superparticles are BPS
Luca Mezincescu, Alasdair J. Routh, Paul K. Townsend
The generic action for an N-extended superparticle in D-dimensional Minkowski spacetime is shown to have "hidden" supersymmetries (related by "dualities" to the manifest supersymme…
