摘要：
It is shown that the BFKL equation is invariant under a gauge-type transformation. As a result one can impose on the Pomeron wave function Psi(rho(1), rho(2)) the colour transparency condition Psi(rho, rho) = 0 valid for functions in the Mobius representation. The triple Pomeron vertex in the multi-colour QCD at this representation is equivalent to the integral kernel in the Balitiski-Kovchegov (BK) equation. As a result, the BK equation for the dipole density is obtained from the nonlinear equation for the sum of fan diagrams.
