Abstract：
the gluon recombination functions in the twist–4 Qcd evolution equations are studied at the leading logarithmic approximation using both the covariant and noncovariant methods.We point out that the gluon recombination functions in the glr–mQ evolution equation are unavailable.the methods avoiding the ir divergences are discussed,which can be used in the derivations of the evolution kernels and coefficient functions at higher twist level.
