Black Holes and Black Rings

The importance of physics in more than four dimensions is emphasized, in particular we are interested in black holes. Spacetimes that describe static and stationary black holes in D = 4 dimensions are introduced as well as black holes and black rings in D = 5. The black ring system shows that uniqueness of D = 4 black holes does not hold in D>4 dimensions. We present, in Weyl's coordinates, a technique to generate D = 5 solutions of Einstein equations in vacuum, some of them can be interpreted as black holes. An example is provided in which starting with Minkowski spacetime, a D = 5 black hole solution is generated.
