We study the problem of construction of global isometric embedding for
spherically symmetric black holes with negative cosmological constant in
various dimensions. Firstly, we show that there is no such embedding for 4D
RN-AdS black hole in 6D flat ambient space, completing the classification which
we started earlier. Then we construct an explicit embedding of non-spinning BTZ
black hole in 6D flat ambient space. Using this embedding as an anzats, we then
construct a global explicit embedding of (d)-dimensional Schwarzschild-AdS
black hole in a flat (d+3)-dimensional ambient space.Comment: 15 page
