The discussion is changed, and a new paragraph is added. A new, quasi-local version of the holographic hypothesis is formulated, and it is explained how it works for physically important classical matter fields in Minkowski spacetime. Two references are added. |
![]() |
Another first order spinor Lagrangian is included. |
![]() |
Two paragraphs in Section 4.2.2 are rewritten, and a gap in the argumentation is filled. |
![]() |
A new reference on the fall-off properties of self-interacting scalar fields in asymptotically anti-de-Sitter spacetimes is added. |
![]() |
The small sphere expression of the Penrose energy in terms of the familiar conformal electric and magnetic parts of the Weyl curvature is given. |
![]() |
A reference on the solutions of the Einstein-Yang-Mills equations that are characterized by the vanishing of the Dougan-Mason mass is added. |
![]() |
A new paragraph about a new (non-scalar) second order Lagrangian, yielding the
trace-![]() |
![]() |
A stronger energy positivity result for the Brown-York energy is included, and the reference is given. |
![]() |
A stronger energy positivity result for the Kijowski-Liu-Yau energy is added, and the reference is given. |
![]() |
A new reference is added. |
![]() |
Section 11.3.2 is rewritten. A more detailed discussion of the Dirichlet and Neumann boundary conditions is given and new references are added. |
![]() |
A new section (Section 11.3.3 in the new version) is opened for a part of the former Section 11.3.2 and for the recent ‘main extrinsic curvature masses’. A new reference is added. |
![]() |
A recent counter-example to the apparent horizon version of the Penrose inequality for non-time-symmetric data sets is mentioned, the discussion is improved and a reference is added. |
![]() |
Two references on the existence of averaged trapped surfaces in non-spherically symmetric data sets are added. |
