Hamiltonian analysis of non-projectable modified F(R) Hořava-Lifshitz gravity
Masud Chaichian, Markku Oksanen, Anca Tureanu
We study a version of the recently proposed modified Hořava-Lifshitz gravity that abandons the projectability condition of the lapse variable. We discovered that the project…
Massless Chiral Supermultiplets of Higher Spins and the -Twistor
M. Chaichian, A. Tureanu, A. A. Zheltukhin
Recently N. Berkovits, motivated by the supertwistor description of super Yang-Mills, considered the generalization of the -twistor constructio…
Modified first-order Horava-Lifshitz gravity: Hamiltonian analysis of the general theory and accelerating FRW cosmology in power-law F(R) model
Sante Carloni, Masud Chaichian, Shin'ichi Nojiri +3
We propose the most general modified first-order Hořava-Lifshitz (HL) gravity, whose action does not contain time derivatives higher than the second order. The Hamiltonian structur…
Modified F(R) Horava-Lifshitz gravity: a way to accelerating FRW cosmology
Masud Chaichian, Shin'ichi Nojiri, Sergei D. Odintsov +2
We propose a general approach for the construction of modified gravity which is invariant under foliation-preserving diffeomorphisms. Special attention is paid to the formulation o…
Covariant star product on symplectic and Poisson spacetime manifolds
M. Chaichian, M. Oksanen, A. Tureanu +1
A covariant Poisson bracket and an associated covariant star product in the sense of deformation quantization are defined on the algebra of tensor-valued differential forms on a sy…
