We suggest a new spin-4 self-dual model (parity singlet) and parity doublet in $D=2+1$. They are of higher order derivatives described by totally symmetric rank-4 tensor without extra auxiliary fields. Despite the they ghost free. find gauge invariant field combinations which allow us to show that canonical structure (spin-3) models follows same pattern its spin-2 (spin-1) counterpart after red...

We present a generally covariant and parity-invariant two-frame field ("zwei-dreibein") action for gravity in three space-time dimensions that propagates two massive spin-2 modes, unitarily, and we use Hamiltonian methods to confirm the absence of unphysical degrees of freedom. We show how zwei-dreibein gravity unifies previous "3D massive gravity" models and extends them, in the context of the...

We show that cosmological topologically massive gravity at the chiral point allows not only Brown–Henneaux boundary conditions as consistent boundary conditions, but slightly more general ones which encompass the logarithmic primary found in 0805.2610 as well as all its descendants. e-mail: [email protected] e-mail: [email protected] Cosmological topologically massive gravity [1] (...
