<dt>Description</dt>
<dd>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.</dd>
