  The role of infrared and ultraviolet renormalons are discussed in context of
leading log(1/x) approximation of perturbative QCD. We generalize the BFKL
equation for the case of running coupling QCD constant and show that the
uncertainties related to the contribution of infrared renormalons turn out to
be smaller than the shadowing correction to the total cross section. The
contribution of infrared and ultraviolet renormalons to the BFKL equation are
studied, and the solution of the BFKL equation with running coupling constant
is discussed.
