Generalised double-logarithmic equation in QCD.


Abstract: We present a generalisation of the double-logarithmic equation for the anomalous dimension of the non-singlet unpolarized twist-2 operators in QCD. Using known three-loop result this generalisation allows to predict a small x expansion of the four-loop non-singlet splitting functions in QCD for all power of logarithms up to single-logarithm ln x
