In this paper we found that the Bose-Einstein enhancement generates thestrong correlations, which increase with energy in the BFKL evolution. Thisincrease leads to the double parton densities ( $\Phi$), that are much largerthan the product of the single parton densities ($\phi$). However, numerically,it turns out that the ratio $\Phi/\phi^2 \propto \Lb 1/x\Rb^{\delta_2}$ with$\delta_2 \sim \bas/\Lb N^2_c - 1\Rb^{2/3}\,\,\ll\,\,1$ and we do not expect alarge correction for the accessible range of energies. However, for $N_c=3$ ittuns out that $\delta_2 = 0.07 \Delta_{\rm BFKL}$ where $\Delta_{\rm BFKL}$ isthe intercept of the BFKL Pomeron and we can anticipate an substantial increasefor the range of rapidities $Y \sim 20$.It is shown that all $1/(N^2_c -1)$corrections to the double parton densities stem from the Bose-Einsteinenhancement.
