Vacuum Einstein metrics with bidimensional Killing leaves.II-Global aspects
G. sparano, G. Vilasi, A. Vinogradov
A formalism (zeta-complex analysis), allowing one to construct global Einstein metrics by matching together local ones described in the papers Phys. Lett. B 513(2001)142-146; Diff.…

Vacuum Einstein metrics with bidimensional Killing leaves. I-Local aspects
G. Sparano, G. Vilasi, A. Vinogradov
The solutions of vacuum Einstein's field equations, for the class of Riemannian metrics admitting a non Abelian bidimensional Lie algebra of Killing fields, are explicitly describe…

Gravitational fields with a non Abelian bidimensional Lie algebra of symmetries
G. Sparano, G. Vilasi, A. M. Vinogradov
Vacuum gravitational fields invariant for a bidimensional non Abelian Lie algebra of Killing fields, are explicitly described. They are parameterized either by solutions of a trans…
