Dimension of the isometry group in type N vacuum solutions: an IDEAL approach
Juan Antonio Sáez, Salvador Mengual, Joan Josep Ferrando
The necessary and sufficient conditions for a type N vacuum solution (with cosmological constant) to admit a group of isometries of dimension are given in terms of the invarian…
Dimension of the isometry group in spacetimes with an invariant frame
Juan Antonio Sáez, Salvador Mengual, Joan Josep Ferrando
The necessary and sufficient conditions for a spacetime with an invariant frame to admit a group of isometries of dimension are given in terms of the connection tensor asso…
Hydrodynamic approach to the Synge gas
Salvador Mengual, Joan Josep Ferrando, Juan Antonio Sáez
The necessary and sufficient conditions for a perfect energy tensor to describe the energy evolutions of a monoatomic relativistic Synge gas are obtained. Then, a Rainich-like theo…
