Complex Metrics on Spacetime

By Edward Witten

Also appears in collection : Fields medallists - 1990

For a variety of reasons, it seems necessary to consider complex saddle points in the "Euclidean'' approach to black hole thermodynamics. But what class of complex saddle points is physically sensible? That will be the subject of this talk.
