The Energy-Momentum Tensor for Gravitational Interactions

Within the Lagrange formalism we show that the gauge invariant total energy-momentum tensor for gravitational interactions is zero. If the equations of motion are satisfied the energy tensor is conserved.

Slice Energy in Higher Order Gravity Theories and Conformal Transformations

We show that there is a generic transport of energy between the scalar field generated by the conformal transformation of higher order gravity theories and the matter component. We give precise relations of this exchange and show that, unless we are in a stationary spacetime, slice energy is not generically conserved. These results translate into statements about the relative behaviour of ordin...

The Energy-momentum Tensor for the Gravitational Field

The search for the gravitational energy-momentum tensor is often qualified as an attempt of looking for “the right answer to the wrong question”. This position does not seem convincing to us. We think that we have found the right answer to the properly formulated question. We have further developed the field theoretical formulation of the general relativity which treats gravity as a non-linear ...

Gravitational Collapse of Homogeneous Perfect Fluids in Higher-order Gravity Theories

This paper investigates the evolution of collapsing FRW models with a scalar field having the potential which arises in the conformal frame of high order gravity theories, coupled to matter described by a perfect fluid with energy density ρ and pressure p, obeying a barotropic equation of state. The solutions are shown to evolve generically to a singular state in a finite time and they are used...

Energy in Generic Higher Curvature Gravity Theories

We define and compute the energy of higher curvature gravity theories in arbitrary dimensions. Generically, these theories admit constant curvature vacua (even in the absence of an explicit cosmological constant), and asymptotically constant curvature solutions with non-trivial energy properties. For concreteness, we study quadratic curvature models in detail. Among them, the one whose action i...
