Abstract
We consider the Bjorken limit in the framework of the effective action appr oach and discuss its similarities to the Regge limit. The proposed effectiv e action allows for a rather simple calculation of the known evolution kern els. We represent the result in terms of two-parton interaction operators i nvolving gluon and quark operators depending on light-ray position and heli city and analyze their symmetry properties.
