Abstract:	The divergence of the photon self-energy diagram in spinor quantum electrodynamics in (2 + 1) dimensional space time- (QEDs) is studied by the Pauli-Villars regularization and dimensional regularization. Results obtained by two different methods are coincided if the gauge invariant of theory is considered carefully step by step in these calculations.
