Conformally reducible 2 + 2 spacetimes

Abstract

Conformally reducible 2 + 2 spacetimes (Carot, Jaume; Tupper, Brian O. J.)

Abstract

Spacetimes which are conformal to 2 + 2 reducible spacetimes are considered. We classify them according to their conformal algebra, giving in each case explicit expressions for the metric and conformal Killing vectors, and providing physically meaningful examples.
