        abstract = {The paper of Lavrent'ev [1] was the beginning of geometrical theory of functions of the complex variable. He solved a problem on the product of conformal radiuses of two non-overlapping domains. In many papers
(see [2] \{ [13]) the Lavrent'ev's result are generalized. In this paper are obtained the new results of this direction.}
