Homomorphisms of projective planes. II.
In part I [Sib. Math. J. 27, 26-34 (1986); translation from Sib. Mat. Zh. 27, No.1(155), 35-44 (1986; Zbl 0594.51002)] the author gave a theoretical background for an investigation of properties of homomorphisms of projective planes. In the paper under review the author gives conditions for the homomorphism to be defined by the subset of the complete pre-image.
