Schwarzschild–De Sitter Thin Shell Wormholes Supported by a Generalized Cosmic Chaplygin Gas

详细

The dynamics of spherically symmetric thin-shell wormholes (TSW), supported by a generalized cosmic Chaplygin gas in Schwarzschild- de Sitter space-time, is studied using the cut-and-paste technique (the Darmois–Israel formalism). A mechanical stability analysis of spherically symmetric thinshell wormhole is is carried out. by using the standard potential method. The existence of stable static solutions depends on the value of some parameters.
