Effective computation of centralizers of ODOs
Antonio Jiménez-Pastor, Sonia L. Rueda
This work is devoted to computing the centralizer of an ordinary differential operator (ODO) in the ring of differential operators. Non-trivial centralizers are known to be…

On the classification of centralizers of ODOs: An effective differential algebra approach
Sonia L Rueda
The correspondence between commutative rings of ordinary differential operators and algebraic curves has been extensively and deeply studied since the seminal works of Burchnall-Ch…
