Abstract

We investigate an alternative to the DGLAP evolution of structure functions through the use of Fixed Order Perturbation Theory. Remarkable agreement between the two methods are found in the polarized sector for a wide x, Q² region. However, for the unpolarized sector the agreement is poorer.
