A gravity theory on noncommutative spaces

- P. Aschieri, Christian Blohmann, M. Dimitrijević, F. Meyer, P. Schupp, J. Wess
- Physics, Mathematics
- 22 April 2005

A deformation of the algebra of diffeomorphisms is constructed for canonically deformed spaces with constant deformation parameter ?. The algebraic relations remain the same, whereas the… Expand

Noncommutative geometry and gravity

- P. Aschieri, M. Dimitrijević, F. Meyer, J. Wess
- Physics, Mathematics
- 6 October 2005

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… Expand

Twisted Gauge Theories

- P. Aschieri, M. Dimitrijević, F. Meyer, S. Schraml, J. Wess
- Mathematics, Physics
- 3 March 2006

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… Expand

Gauge theories on the κ-Minkowski spacetime

- M. Dimitrijević, F. Meyer, L. Möller, J. Wess
- 2005

This study of gauge field theories on κ-deformed Minkowski spacetime extends previous work on field theories on this example of a noncommutative spacetime. We construct deformed gauge theories for… Expand

Gauge Theory on Twisted $\kappa$-Minkowski: Old Problems and Possible Solutions

- M. Dimitrijević, L. Jonke, A. Pachoł
- Mathematics, Physics
- 7 March 2014

We review the application of twist deformation formalism and the construction of noncommutative gauge theory on $\kappa$-Minkowski space-time. We compare two different types of twists: the Abelian… Expand

Noncommutative SO(2,3) gauge theory and noncommutative gravity

- M. Dimitrijević, V. Radovanovi'c
- Physics
- 16 April 2014

In this paper noncommutative gravity is constructed as a gauge theory of the noncommutative $SO(2,3{)}_{$\star${}}$ group, while the noncommutativity is canonical (constant). The Seiberg-Witten map… Expand

(Non)renormalizability of the D -deformed Wess-Zumino model

- M. Dimitrijević, B. Nikolić, V. Radovanovi'c
- Physics
- 15 January 2010

We continue the analysis of the D-deformed Wess-Zumino model that we introduced in M. Dmitrijevic and V. Radovanovic, J. High Energy Phys. 04 (2009) 108. The model is defined by a deformation that is… Expand

Deformed Bialgebra of Diffeomorphisms

- M. Dimitrijević, J. Wess
- Physics
- 24 November 2004

The algebra of diffeomorphisms derived from general coordinate transformations on commuting coordinates is represented by differential operators on noncommutative spaces. The algebra remains… Expand

Dynamical Noncommutativity and Noether Theorem in Twisted $${\phi^{\star 4}}$$ Theory

- P. Aschieri, L. Castellani, M. Dimitrijević
- Physics
- 30 March 2008

A $${\star}$$-product is defined via a set of commuting vector fields $${X_a = {e_a} ^{\mu} (x) \partial_\mu}$$, and used in a $${\phi^{\star 4}}$$ theory coupled to the $${{e_a} ^{\mu} (x)}$$… Expand
