Abstract

We show that a unified approach to the perturbative evolution of structure functions which sums all logarithms of Q² and 1/x at leading and next-to-leading order yields results in full agreement with the 1993 HERA data for F₂. This makes it possible to determine alpha_s surprisingly accurately from these data alone.
