Abstract
We present a detailed study of the bare pomeron graph in two-dimensional QCD in the 1/Nc approximation. The absence of a new singularity unrelated to quark parameters is derived. The "cylinder" graph is shown to induce renormalization of the vertex and intercept associated with quark andti-quark exchange in the vacuum channel.
