Hermite Reduction for D-finite Functions via Integral Bases
Shaoshi Chen, Lixin Du, Manuel Kauers · 2023
Trager’s Hermite reduction solves the integration problem for algebraic functions via integral bases. A generalization of this algorithm to D-finite functions has so far been limited to the Fuchsian case. In the present paper, we remove this restriction and propose a reduction algorithm based on integral bases that is applicable to arbitrary D-finite functions.
