Abstract

We derive an equation determining the small-$x$ evolution of the ${F}_{2}$ structure function of a large nucleus which includes all multiple Pomeron exchanges in the leading logarithmic approximation using Mueller's dipole model. We show that in the double leading logarithmic limit this evolution equation reduces to the Gribov-Levin-Ryskin equation.
