abstract
We analyze quantization of noncommutative chiral electrodynamics in the enveloping algebra formalism in linear order in noncommutativity parameter $\theta$. Calculations show that divergences exist and cannot be removed by ordinary renormalization, however they can be removed by the Seiberg-Witten redefinition of fields. Performing the redefinitions explicitly, we obtain renormalizable lagrangian and discuss the influence of noncommutativity on field propagation. Noncommutativity affects the propagation of chiral fermions only: half of the fermionic modes become massive and birefringent.

Fermion quasinormal modes on modified RN background
Charged massless fermion quasinormal modes in a noncommutatively deformed Reissner-Nordström black hole show a linear, azimuthal-quantum-number-dependent splitting of the complex mode frequencies.
