Gravitation vs. Rotation in 2+1 Dimensions

TL;DR

This paper explores the effects of rotation in (2+1)-dimensional Einstein gravity, revealing that rotation often results in physically problematic scenarios.

Contribution

It demonstrates that rotation in (2+1)-dimensional Einstein gravity typically causes pathological physical conditions, highlighting limitations of rotating solutions.

Findings

Rotation often leads to unphysical situations.

Rotating structures in (2+1)D Einstein gravity are generally problematic.

Abstract

We investigate rotation and rotating structures in (2+1)-dimensional Einstein gravity. We show that rotation generally leads to pathological physical situations.
