Название: On the factorisation of linear ordinary differential operators
Автор: Bronstein M.
After reviewing the arithmetic of linear ordinary differential operators, we describe the current status of the factorisation algorithm, specially with respect to factoring over non-algebraical I > closed constant fields. We also describe recent results from Singer and Ulmer (1993) that reduce determining the differential Galois group of an operator to factoring.
