Abstract
It is shown that in the leading twist approximation of the Wilson operator product expansion with "frozen" and analytic strong coupling constants, considering the Bessel-inspired behavior of the structure functions F2 and the derivative d ln F2/(d ln(1/x)) at small x values, obtained for a flat initial condition in the DGLAP evolution equations,leads to a good agreement with the deep inelastic scattering H1 and ZEUS experimental data from HERA
