要旨:
We discuss a general procedure to generate a class of (everywhere regular)
solutions of Einstein equations that can have an (a-priori fixed) arbitrary
number of horizons. We then report on work currently in progress i) to find a
suitable classification scheme for the maximal extension of these solutions and
ii) to interpret the source term in Einstein equations as an effective
contribution arising from higher dimensional and/or modified gravity.
