    Abstract

    We use Lorentz invariance and the QCD equations of motion to study the evolution of functions that appear at leading order in a 1/0 expansion in azimuthal asymmetries. This includes the evolution equation of the Collins fragmentation function. The moments of these functions are matrix elements of known twist two and twist three operators. We present the evolution in the large N
