  In this paper we address two problems in the BFKL Pomeron calculus in zero
transverse dimensions: the summation of the Pomeron loops and the calculation
of the processes of multiparticle generation. We introduce a new generating
functional for these processes and obtain the evolution equation for it. We
argue that in the kinematic range given by $ 1 \ll \ln(1/\as^2) \ll \as Y \ll
\frac{1}{\as}$, we can reduce the Pomeron calculus to exchange of
non-interacting Pomerons with the renormalized amplitude of their interaction
with the target. Therefore, the summation of the Pomeron loops can be performed
using Mueller, Patel, Salam and Iancu approximation.
