    abstract = {We compute the logarithmic contributions to the polarized massive Wilson coefficients for deep-inelastic scattering in the asymptotic region $Q^2\gg m^2$ to 3-loop order in the fixed- flavor number scheme and present the corresponding expressions for the polarized massive operator matrix elements needed in the variable flavor number scheme. The calculation is performed in the Larin scheme. For the massive operator matrix elements $A_{qq,Q}^{(3),PS}$ and $A_{qg,Q}^{(3),S}$ the complete results are presented. The expressions are given in Mellin-$N$ space and in momentum fraction $z$-space.},
