TY - JOUR ID - 1339723 AU - Klusoň, Josef - Chaichian, Masud - Oksanen, Markku PY - 2015 TI - Nonprojectable Horava-Lifshitz gravity without the unwanted scalar graviton JF - Physical review D VL - 92 IS - 10 SP - "nestránkováno" EP - "nestránkováno" PB - American Physical Society SN - 15507998 KW - Gravitation KW - Hamiltonian Formalism N2 - We consider a way of eliminating the unwanted scalar graviton from Horava-Lifshitz gravity that is achieved via introduction of certain additional constraints. We perform canonical analysis of both projectable and nonprojectable versions of the theory. We obtain the structure of constraints in each case, and analyze its dependence on the values of the coupling constants involved in the additional constraints. In the nonprojectable theory, the scalar graviton is absent when the coupling constants have certain values, while for other values the scalar graviton appears. The projectable theory is free from the scalar graviton regardless of the values of the coupling constants, even though the structure of the constraints does depend on the value of a coupling constant.
