We study a spectral representation of the BFKL kernel not defined on the Moebius space of functions but on a deformation of it, which provides the usual bootstrap property due to gluon reggeization. In this space the corresponding symmetry is made explicit introducing a deformed realization of the sl(2,C) algebra.4 pages, Talk on XIth International Conference on Elastic and Diffractive Scattering (EDS05),Chateau de Blois (France), 15-20 May 2005High Energy Physics - Phenomenologytext
