摘要：

The non-singlet and singlet evolution kernels of the twist-2 light-ray operators for unpolarized and polarized deep inelastic scattering are calculated in O(alpha(s)) for the general case of virtualities q(2), q'(2) not equal 0. Special cases as the kernels for the general single-variable evolution equation and the Altarelli-Parisi and Brodsky-Lepage limits are derived from these results.
