A Fundamental Theorem of Space-times
E. M. Monte, M. D. Maia
The fundamental theorem of submanifolds is adapted to space-times. It is shown that the integrability conditions for the existence of submanifolds of a pseudo-Euclidean space conta…
A Model for Stars of Interacting Bosons and Fermions
Claudio M. G. de Sousa, J. L. Tomazelli
In this paper we introduce a current-current type interaction term in the Lagrangian density of gravity coupled to complex scalar fields, in the presence of a degenerated Fermi gas…
Gravitational energy of conical defects
J. W. Maluf, A. Kneip
The energy density of asymptotically flat gravitational fields can be calculated from a simple expression involving the trace of the torsion tensor. Integration of this energy dens…
Localization of Energy in General Relativity
Jose W. Maluf
In the framework of the teleparallel equivalent of general relativity the energy density of asymptoticaly flat gravitational fields can be naturally and unambiguously defined. Upon…
The Signature Problem for Embedded Space-times
M. D. Maia, E. M. Monte
The compatibility between the general relativity and the mathematical property that the space-times are embedded manifolds are further examined. In particular we study the uniquene…
