(2 + 1)-dimensional Schwarzschild-de Sitter wormhole

Abstract

In the (2 + 1)-dimensional spacetime two pieces of the Schwarzschild-de Sitter spacetime are connected to form a Schwarzschild-de Sitter type wormhole using the (2 + 1)-dimensional Schwarzschild-de Sitter metric. The dynamical stabilities for this type of wormhole are discussed and compared with those of other cases, such as the (3 + 1)-dimensional Schwarzschild-de Sitter type wormhole and the (2 + 1)-dimensional Schwarzschild type wormhole. © 1993.
