Abstract
The terms to the massive gluonic operator matrix elements are calculated for general values of the Mellin variable . These twist-2 matrix elements occur as transition functions in the variable flavor number scheme at NNLO. The calculation uses sum-representations in generalized hypergeometric series turning into harmonic sums. The analytic continuation to complex values of is provided.
