Abstract: (Elsevier)

Large N singularities of parton densities are related by a gauge transformation to a class of collinear singularities. We prove on this basis that the effective anomalous dimension shows [ α S ( Q 2 ) log N ] p singularities which are calculable to all orders by a change of scale in α S ( Q 2 ).
