We present a three-dimensional Chern-Simons gravity based on a deformation of the Maxwell algebra. This symmetry allows introduction of a non-vanishing torsion to the Maxwell Chern-Simons theory, whose action recovers the Mielke-Baelker model for particular values of the coupling constants. By ...
在Chern-Simons理论中,Chern-Simons形式的一般定义为:\[ CS(A) = \text{Tr}\left(A \wedge dA + \frac{2}{3}A \wedge A \wedge A\right) \]在我们的场景中,联络A的数学表达式为\(A = v \cdot \cos(\theta) d\phi\),而曲率F的数学表达式为\(F = -v \cdot \sin(\theta) d\theta \wed...
2 Maxwell Chern–Simons gravity theory with torsion Using the CS formalism, we present the three-dimensional gravity theory based on a particular deformation of the Maxwell algebra. Unlike the Maxwell case, such deforma- tion leads to a non-vanishing torsion as equation of motion. The deformed ...
The evolution of $ilde {w} $ in a flat FRW universe is studied, and it is shown that the parameters of the theory admit solutions wherein it is possible to have an equation of state $p_\\\phi \\\approx -\\\epsilon_\\\phi $, so that it leads to an accelerating universe. We ...

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-Cartan Gravity, General Massive Gravity, the recently proposed Zwei-Dreibein Gravity and a further parity violating ge...
It is shown that topological massive gravity augmented by the triadic gravitational Chern-Simons first order term is a curved a pure spin-2 action. This model contains two massive spin-2 excitations. However, since its light-front energy is not semidefinite positive, this double CS-action does ...
