Numerical solution of NLO Q^2 evolution equations for spin-dependent structure functions
Abstract
Numerical solution of DGLAP evolution equations is studied for polarized parton distributions by using a ``brute-force" method. NLO contributions to splitting functions are recently calculated,and they are included in our analysis. Numerical results in polarized parton distributions and in the structure function are shown. In particular, we discuss how numerical accuracy depends on number of steps in the variable and in .
