(N+1)-dimensional Lorentzian evolving wormholes supported by polytropic matter

Abstract

In this paper we study (N+1)-dimensional evolving wormholes supported by energy satisfying a polytropic equation of state. The considered evolving wormhole models are described by a constant redshift function and generalizes the standard flat Friedmann-Robertson-Walker spacetime. The polytropic equation of state allows us to consider in (3+1)-dimensions generalizations of the phantom energy and the generalized Chaplygin gas sources. © 2013 Springer-Verlag Berlin Heidelberg and Società Italiana di Fisica.
