Abstract

The present status of the measurements of hadronic structure functions of the photon, investigated in deep inelastic electron-photon scattering at LEP, is presented. This article covers the hadronic structure function F_2^gamma of quasi-real photons as well as the structure function of virtual photons. Special emphasis is given to new developments in the analysis and to the most recent measurements.
