Abstract
Starting from linear equations for the complex scalar field, the two- and three-point Green's functions are obtained in the infrared approxi mation. We show that the infrared singularity factorizes in the vertex function as in spinor QED, reproducing in a simple and straightforwar d way the result of lengthy perturbative calculations.
