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

TL;DR

This paper explores higher-dimensional evolving wormholes supported by polytropic matter, generalizing known cosmological models and providing new insights into exotic matter sources like phantom energy and Chaplygin gas.

Contribution

It introduces a class of $(N+1)$-dimensional evolving wormholes with a polytropic equation of state, extending previous models to higher dimensions and more general matter sources.

Findings

Models include generalizations of phantom energy and Chaplygin gas.

The wormholes are described by a constant redshift function.

The models extend standard flat FRW spacetime to higher dimensions.

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.
