The solution to the non-forward BFKL equation in the Leading Logarithmicapproximation is expressed in terms of a sum of iterations of its kerneldirectly in transverse momentum and rapidity space. Several studies of thenon-forward solution are performed both at the level of the gluon Green'sfunction and for a toy cross-section, including an analysis of the diffusionproperties as found in this approach. The method developed in this paper allowsfor a direct inspection of the momenta in the BFKL ladder, and can be appliedto solving the non-forward BFKL equation to next-to-leading logarithmicaccuracy, when the corresponding kernel is available.Comment: 15 page
