Abstract
We describe the calculation of the evolution of the
gluon density in x from an initial value x=x0=0.01 to smaller
values, up to x=10-8 in the hard pomeron formalism with a running
coupling introduced on the basis of the bootstrap equation.
The obtained gluon density is used to calculate the singlet part of the
proton structure function. Comparison with experiment and the results
following from the fixed coupling evolution is made.
