Abstract
The BFKL and the unified angular-ordered equations are solved to deter mine the gluon distribution at small x. The impact of kinematic constr aints is investigated. Predictions are made for observables sensitive to the gluon at small x. In particular comparison is made with measure ments at the HERA electron-proton collider of the proton structure fun ction F-2(x, Q(2)) as a function of In Q(2), the charm component, F-2( c)(x, Q(2)) and diffractive J/psi photoproduction.
