Possible Wormhole Solutions in (4+1) Gravity

TL;DR

This paper explores new parameter ranges for wormhole solutions in five-dimensional gravity, showing they are less exotic and have positive gravitational mass, expanding understanding of higher-dimensional wormholes.

Contribution

It extends previous (4+1) gravity analyses to new parameters, demonstrating the existence of less exotic wormholes with positive mass.

Findings

Wormholes in (4+1) gravity have topology similar to (3+1) wormholes.

The matter does not satisfy strong energy conditions.

Gravitational mass of these wormholes is positive.

Abstract

We extend previous analyses of soliton solutions in (4+1) gravity to new ranges of their defining parameters. The geometry, as studied using invariants, has the topology of wormholes found in (3+1) gravity. In the induced-matter picture, the fluid does not satisfy the strong energy conditions, but its gravitational mass is positive. We infer the possible existance of (4+1) wormholes which, compared to their (3+1) counterparts, are less exotic.
