Finite-term recurrences in a generalized Bochner--Krall family
L. M. Anguas, D. Barrios Rolanía, B. Shapiro +1
We classify the differential operators \(T=z^j\partial_z^j+z^m\partial_z^\ell\), where \(0\le m<\ell\) and \(1\le j<\ell\), whose monic eigenpolynomials satisfy a finite-term recur…

New tools for the study of Bochner differential operators
L. M. Anguas, D. Barrios Rolanía
A sequence associated to a Bochner differential operator is introduced as an effective tool to study this kind of operators. Some properties of this sequence are pr…
