Partonic Structure of the Pomeron
  The first measurement of diffractive processes in deep inelastic scattering at the HERA collider is analysed in terms of a "soft" pomeron exchange model. The partonic structure of the pomeron which emerges in this picture is determined using the QCD parton model. The important role of the gluonic component in the partonic interpretation of the data is particularly emphasized.
