Green function of the BFKL equation and the DGLAP limit
**

We consider the problem of constructing the Green function for the BFKL equation in the next-to-leading approximation, where the running coupling constant effects are essential. In the semi-classical approximation the Green function is expressed in terms of the Eiry functions which takes into account the infrared boundary conditions. We consider different models in the infrared region and investigate the transition to the Bjorken kinematics.
