We derive noncommutative Einstein equations for abelian twists and their solutions in consistently symmetry reduced sectors, corresponding to twisted FRW cosmology and Schwarzschild black holes. While some of these solutions must be rejected as model... Read More about Cosmological and Black Hole Spacetimes in Twisted Noncommutative Gravity.

Symmetry Reduction and Exact Solutions in Twisted Noncommutative Gravity (2009)
Journal Article
Schenkel, A. (2009). Symmetry Reduction and Exact Solutions in Twisted Noncommutative Gravity. Acta Physica Polonica B Proceedings Supplement, 2(3), 657-667

We review the noncommutative gravity of Wess et al. and discuss its physical applications. We define noncommutative symmetry reduction and construct deformed symmetric solutions of the noncommutative Einstein equations. We apply our framework to find...

As a preparation for a mathematically consistent study of the physics of symmetric spacetimes in a noncommutative setting, we study symmetry reductions in deformed gravity. We focus on deformations that are given by a twist of a Lie algebra acting on... Read More about Symmetry Reduction in Twisted Noncommutative Gravity with Applications to Cosmology and Black Holes.
