Marginally Trapped Surfaces in the Nonsymmetric Gravitational Theory

TL;DR

This paper investigates the existence of marginally trapped surfaces within the Nonsymmetric Gravitational Theory by analyzing a specific spherically symmetric gravitational field with an antisymmetric field pulse.

Contribution

It introduces a physical approach to identifying marginally trapped surfaces in NGT and demonstrates their existence in a particular spherically symmetric scenario.

Findings

Marginally trapped surfaces exist in the studied NGT scenario.

The approach can be applied to other NGT configurations.

Supports the physical relevance of trapped surfaces in NGT.

Abstract

We consider a simple, physical approach to the problem of marginally trapped surfaces in the Nonsymmetric Gravitational Theory (NGT). We apply this approach to a particular spherically symmetric, Wyman sector gravitational field, consisting of a pulse in the antisymmetric field variable. We demonstrate that marginally trapped surfaces do exist for this choice of initial data.
