On the invariant symmetries of the -metrics
Joan Josep Ferrando, Juan Antonio Sáez
We analyze the symmetries and other invariant qualities of the -metrics (type D aligned Einstein Maxwell solutions with cosmological constant whose Debever null princi…
Creatable Universes
Joan Josep Ferrando, Ramon Lapiedra, Juan Antonio Morales
We consider the question of properly defining energy and momenta for non asymptotic Minkowskian spaces in general relativity. Only spaces of this type, whose energy, linear 3-momen…
Rainich theory for type D aligned Einstein-Maxwell solutions
Joan Josep Ferrando, Juan Antonio Sáez
The original Rainich theory for the non-null Einstein-Maxwell solutions consists of a set of algebraic conditions and the Rainich (differential) equation. We show here that the sub…
