AbstractAbstract
[en] The approach based on the diagrammatic analysis is applied to study the structure of the evolution kernel and to solve the evolution equation. The general structure of the two-loop non forward evolution kernels is investigated in the phisub((6))sup(3)-model and QCD. The solution of the two-loop evolution equations is constructed in both models. In QCD, the contribution of the two-loop corrections to the wave function evolution is estimated numerically. The methods developed can be applied to obtain the evolution of wave function related to other hadrons. The results obtained can be applied directly for calculations of any exclusive processes involving pions
