Description
Two models for the region of small transverse momenta in the BFKL equation are discussed. In the first of them the gluons are massive as a result of the Higgs mechanizm. For the second case the
impact parameter space is compactified, which can serve as a model for the confinement based on the dual Meissner effect. Further, the non-Fredholm properties of the BFKL kernel at the
collinear kinematics in the t-channel allow us to calculate its eigenvalues in a semi-classical approximation for N=4 SUSY in all orders of perturbation theory.
