The bootstrap and the 2nd order corrections for the interaction of two reggeized gluons

The bootstrap relation is discussed up to the 2nd order. From the strong bootstrap condition and a specific ansatz to solve it the 2nd order corrections are obtained to both forward and nonforward interaction of reggeized gluons in the octet colour channel. The obtained forward kernel coincides with the logarithmic term plus two first non-logarithmic terms in the Pomeron 2nd order kernel. Both forward and nonforward kernels are found to be infrared finite.
