Query: On Renormalons and Landau Poles in Gauge Field Theories   It is shown that the commonly accepted relationship between the Landau
singularity in the running coupling constant of QED or QCD and the renormalon
singularities in the Borel sums of perturbation theory expansions is only a
particular feature of the restriction of the perturbative $\beta$--function to
the one loop level.
