We discuss the perturbatively calculable virtual photon structure functions. First we present the framework for analyzing the structure functions of the virtual photon and derive a first moment of g~ of the virtual photon. We then investigate the three positivity constraints satisfied by the eight s

The hadronic photon structure function from the LEP experiments will be reviewed. Since the 1998 Lund meeting new results from the ALEPH, L3 and OPAL collaborations have become available. The LEP data now cover a large range in x and Q2. At high Q2 the agreement with the theoretical predictions gets

We calculate the first moment of the photon structure function, (x)' = si dzF,Y(z,Q2), on the lattice using the formalism developed by the authors. Different lattice spacings and volumes are studied to estimate the systematic errors present in lattice simulations. Also, the Nf = 2 dynamical configur
