Virtual Photon Structure Functions

Abstract

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 $g_1^{\gamma }$ of the virtual photon. We then investigate the three positivity constraints satisfied by the eight structure functions of the virtual photon.
