### Abstract

Photon structure functions for massive quarks (i.e. i=Q-c, b, . . .) should be suppressed compared to f_{u,d,s} gamma / by the screening of the evolution up to the scale Q^{2}=Q_{0}^{2} of order of the heavy flavour mass-squared,/sup /m_{Q}^{2}. Contrary to light quarks, one can safely ignore the non-point-like hadronic contributions for photon structure functions of massive quarks since the effect of VMD for photon structure functions rapidly decreases as Q^{2} (or m _{Q}^{2}) increases, i.e. Q^{2}>>m _{rho}^{2}.
