We give a simplified formula for the star product on , which enables us to define a twist element suited for discussing a Drinfeld twist like structure on fuzzy complex projective spaces. The existence of such a twist will have several consequences for field theories on fuzzy spaces, some of which we discuss in the present paper. As expected, we find that the twist of the coproduct is trivial for the generators of isometries on . Furthermore, the twist allows us to define a covariant tensor… 

Star Products that can not be induced by Drinfel'd Twists

This is the final version of my master thesis. I prove that there are no twist star products on the 2-sphere and on the higher genus pretzel surfaces deforming a symplectic structure. One of the key

Tensor calculus on noncommutative spaces

It is well known that for a given Poisson structure one has infinitely many star products related through the Kontsevich gauge transformations. These gauge transformations have an infinite functional

Noncommutative vector bundles over fuzzy CP N and their covariant derivatives

We generalise the construction of fuzzy CP N in a manner that allows us to access all noncommutative equivariant complex vector bundles over this space. We give a simplified construction of

Fuzzy toric geometries

It is shown that the fuzzification of a projective toric variety amounts to a quantization of its toric base, and one can easily obtain large classes of fuzzy Calabi-Yau manifolds.

Quantization of flag manifolds and their supersymmetric extensions

We first review the description of flag manifolds in terms of Plucker coordinates and coherent states. Using this description, we construct fuzzy versions of the algebra of functions on these spaces

Noncommutative gravity

We consider simple extensions of noncommutativity from flat to curved spacetime. One possibility is to have a generalization of the Moyal product with a covariantly constant noncommutative tensor

Star product and invariant integration for Lie Type noncommutative spacetimes

We present a star product for noncommutative spaces of Lie type, including the so called ``canonical'' case by introducing a central generator, which is compatible with translations and admits a

Field Theory on Curved Noncommutative Spacetimes

We study classical scalar field theories on noncommutative curved spacetimes. Following the approach of Wess et al. (Classical Quantum Gravity 22 (2005), 3511 and Classical Quantum Gravity 23 (2006),

Gauge theory models on κ-Minkowski space: Results and prospects

Recent results obtained in κ-Poincaré invariant gauge theories on κ-Minkowski space are reviewed and commented. A Weyl quantization procedure can be applied to convolution algebras to derive a

In this paper, using a Hopf-algebraic method, we construct deformed Poincare SUSY algebra in terms of twisted (Hopf) algebra. By adapting this twist deformed super-Poincare algebra as our fundamental

Noncommutative geometry and twisted conformal symmetry

The twist-deformed conformal algebra is constructed as a Hopf algebra with twisted coproduct. This allows for the definition of conformal symmetry in a noncommutative background geometry. The twisted

We study a deformation of infinitesimal diffeomorphisms of a smooth manifold. The deformation is based on a general twist. This leads to a differential geometry on a noncommutative algebra of

Twisted Gauge Theories

Gauge theories on a space-time that is deformed by the Moyal–Weyl product are constructed by twisting the coproduct for gauge transformations. This way a deformed Leibniz rule is obtained, which is
