Global embedding of BTZ spacetime using generalized method of symmetric embeddings construction
A. A. Sheykin, M. V. Markov, S. A. Paston
It is often easier to study pseudo-Riemannian manifolds by presenting them as surfaces in some ambient space. We propose an algorithm for construction of explicit isometric embeddi…

Explicit isometric embeddings of pseudo-Riemannian manifolds: ideas and applications
A. A. Sheykin, M. V. Markov, Ya. A. Fedulov +1
We study the problem of construction of explicit isometric embeddings of (pseudo)-Riemannian manifolds. We discuss the method which is based in the idea that the exterior symmetry…
