      abstract     = {We consider the (process-independent) Green function for
                      the BFKL equation with running coupling, and explain how,
                      within the semi-classical approximation, it is related to
                      Green function of the Airy equation. The unique Green
                      function is obtained from a combination of its required
                      ultraviolet behaviour compatible with asymptotic freedom and
                      an infrared limit phase imposed by the non-perturbative
                      sector of QCD. We show that at sufficiently large gluon
                      transverse momenta the corresponding gluon density matches
                      that of the DGLAP analysis, whereas for relatively small
                      values of the gluon transverse momentum the gluon
                      distribution is sensitive to the Regge poles, whose
                      positions are determined both by the non-perturbative QCD
                      dynamics and physics at large transverse momenta.},
