Abstract The non-commutative extension of a dynamical 2-dimensional space–time is given and some of its properties discussed. Wick rotation to Euclidean signature yields a surface which has as commutative limit the doughnut but in a singular limit in which the radius of the hole tends to zero. 
Spherically symmetric non-commutative space: d=4
In order to find a non-commutative analog of Schwarzschild or Schwarzschild–de Sitter black hole we investigate spherically symmetric spaces generated by four non-commutative coordinates in the frame
Gravity and the structure of noncommutative algebras
A gravitational field can be defined in terms of a moving frame, which when made noncommutative yields a preferred basis for a differential calculus. It is conjectured that to a linear perturbation
Noncommutative geometry of phase space
A version of noncommutative geometry is proposed which is based on phase-space rather than position space. The momenta encode the information contained in the algebra of forms by a map which is the
Gravity and the Structure of Noncommutative
A gravitational field can be defined in terms of a moving frame, which when made noncommutative yields a preferred basis for a differential calculus. It is conjectured that to a linear perturbation
WKB Approximation in Noncommutative Gravity
We consider the quasi-commutative approximation to a noncommutative geo- metry defined as a generalization of the moving frame formalism. The relation which exists between noncommutativity and

Two roads to noncommutative causality
We review the physical motivations and the mathematical results obtained so far in the isocone-based approach to noncommutative causality. We also give a briefer account of the alternative framework
Line element in quantum gravity: the examples of DSR and noncommutative geometry
We question the notion of line element in some quantum spaces that are expected to play a role in quantum gravity, namely non-commutative deformations of Minkowski spaces. We recall how the
The energy-momentum of a Poisson structure
Consider the quasi-commutative approximation to a noncommutative geometry. It is shown that there is a natural map from the resulting Poisson structure to the Riemann curvature of a metric. This map
Fuzzy de Sitter space
We discuss properties of fuzzy de Sitter space defined by means of algebra of the de Sitter group $$\text {SO}(1,4)$$SO(1,4) in unitary irreducible representations. It was shown before that this

Abstract In previous articles it has been argued that a differential calculus over a noncommutative algebra uniquely determines a gravitational field in the commutative limit and that there is a
On Curvature in Noncommutative Geometry
A general definition of a bimodule connection in noncommutative geometry has been recently proposed. For a given algebra this definition is compared with the ordinary definition of a connection on a
Automorphisms of associative algebras and noncommutative geometry
A class of differential calculi is explored which is determined by a set of automorphisms of the underlying associative algebra. Several examples are presented. In particular, differential calculi on

A model of Euclidean spacetime is presented in which at scales less than a certain length kappa the notion of a point does not exist. At scales larger then kappa the model resembles the 2-sphere S2.

A construction is proposed for linear connections on non-commutative algebras. The construction relies on a generalization of the Leibniz rules of commutative geometry and uses the bimodule structure

Abstract: We apply one of the formalisms of noncommutative geometry to ℝNq, the quantum space covariant under the quantum group SOq(N). Over ℝNq there are two SOq(N)-covariant differential calculi.

TLDR
Evaluation of the ADM mass, as a charge density integral, is possible in some situations by carefully subtracting the black hole solution from the corresponding linear dilation at infinity.
