A Gravity Theory on Noncommutative Spaces
Paolo Aschieri, Christian Blohmann, Marija Dimitrijevic +3
A deformation of the algebra of diffeomorphisms is constructed for canonically deformed spaces with constant deformation parameter theta. The algebraic relations remain the same, w…
Renormalizable Theories from Fuzzy Higher Dimensions
Paolo Aschieri, John Madore, Pantelis Manousselis +1
We consider gauge theories defined in higher dimensions where the extra dimensions form a fuzzy space (a finite matrix manifold). We reinterpret these gauge theories as four-dimens…
Noncommutative gerbes and deformation quantization
Paolo Aschieri, Igor Bakovic, Branislav Jurco +1
We define noncommutative gerbes using the language of star products. Quantized twisted Poisson structures are discussed as an explicit realization in the sense of deformation quant…
