In this paper we derive two second-order differential equations for the gluon and singlet distribution functions by using the Laplace transform method. We decoupled the solutions of the singlet and gluon distributions into the initial conditions (function and derivative of the function) at the virtuality Q 0 2 separately as these solutions are defined by F 2 s (x, Q 2) = F(F 0 ,∂F s0 and G(x, Q 2)=G(G 0, ∂G 0. We compared our results with the MSTW parameterization and the experimental measurements of F 2 p (x, Q 2.
