In this thesis, we extended the description of the contributions of a single heavy quark to the unpolarized Wilson coefficients \({\mathcal C}_{(q,g),2}^{ S,PS,NS}\) to \(O(a_s^3)\). In upcoming precision analyzes of deep-inelastic data, this will allow more precise determinations of parton distribution functions and of the strong coupling constant.
