# Towards noncommutative fuzzy QED

@article{DelgadilloBlando2006TowardsNF, title={Towards noncommutative fuzzy QED}, author={Rodrigo Delgadillo-Blando and Badis Ydri}, journal={Journal of High Energy Physics}, year={2006}, volume={2007}, pages={056-056} }

We study in one-loop perturbation theory noncommutative fuzzy quenched QED4. We write down the effective action on fuzzy S2 ? S2 and show the existence of a gauge-invariant UV-IR mixing in the model in the large N planar limit. We also give a derivation of the beta function and comment on the limit of large mass of the normal scalar fields. We also discuss topology change in this 4 fuzzy dimensions arising from the interaction of fields (matrices) with spacetime through its noncommutativity.
