The Global Embedding Problem of Semi-Riemannian into Einstein Manifolds

arXiv:math-ph/0407067

Abstract

We show that every analytic semi-Riemannian manifold can be isometrically embeddded into an Einstein maifold in co-dimension one.

There has been discovered a misconseption which does not allow the solvability of the algebraic systems arising in the proof without further topological assumptions on the manifold
