Query: On the n -> 0 limit of gamma_gg(a) in QCD   We consider the n -> 0 limit of the DGLAP splitting function gamma_gg(a) at
all orders in the strong coupling constant, a, by analysing the leading order
large N_f form of the associated d-dimensional critical exponent. We show that
for unpolarized scattering the pole at n = 0 which appears in successive orders
in perturbation theory is absent in the resummed expression.
