Abstract
We review evolution equations for truncated Mellin moments (TMM) of the parton densities. The main finding of the presented approach is that the nth truncated moment of the parton distribution obeys the DGLAP-like equation, with a rescaled splitting function P′(z) = znP(z). This approach allows one to restrict the analysis to the experimentally available Bjorken-x region. We present some applications of TMM to study the spin structure functions of the nucleon.
