Slice Energy and Conformal Frames in Theories of Gravitation

  title={Slice Energy and Conformal Frames in Theories of Gravitation},
  author={Spiros Cotsakis},
We examine and compare the behaviour of the scalar field slice energy in different classes of theories of gravity, in particular higher-order and scalar-tensor theories. We find a universal formula for the energy and compare the resulting conservation laws with those known in general relativity. This leads to a comparison between the inflaton, the dilaton and other forms of scalar fields present in these generalized theories. It also shows that all such conformally-related, generalized theories… CONTINUE READING
