As an example, the two-dimensional space-time noncommutative QED (NC-QED) is quantized perturbatively up to O(e^2,\\theta^3), where e is the NC-QED coupling constant and \\theta is the noncommutativity parameter. The resulting modified Lagrangian density is shown to include terms consisting of first order time-derivative and higher order space-derivatives of t","authors_text":"M. Ghasemkhani, N.
