Abstract
The integral equation leading to the perturbative vacuum singularity ( Lipatov pomeron) intercept in quantum chromodynamics is modified by re placing the massless gluon propagator by diverse expressions motivated by the inclusion of non-perturbative effects. It is found that with s uitable values of the parameters in the modified gluon propagator it i s possible to obtain a pomeron intercept equal to that of the usual no n-perturbative one.
