Abstract
We describe the calculation of the evolution of the gluon density in x from an initial value x = x(0) = 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. C omparison with experiment and the results following from the fixed cou pling evolution is made.
