Rings of differential operators over rational affine curves
This paper deals with the rings which satisfy condition. This notion has been introduced recently by R. Dastanpour and A. Ghorbani (2017) as a generalization of Artnian rings. It is of interest to investigate more deeply this class of rings. This study focuses on commutative case. In this vein, we present this work in which we examine the transfer of these rings to the trivial, amalgamation and polynomial ring extensions. We also investigate the relationship between this class of rings and the...
Let be a Noetherian ring, and and be two ideals of . Let be a Serre subcategory of the category of -modules satisfying the condition and be a -module. As a generalization of the - and , the - of on is defined as --, and some properties of this concept are investigated. The relations between - and are studied, and it is proved that -, where is a Serre subcategory closed under taking injective hulls. Some conditions are provided that local cohomology modules with...
We describe the branching rule from to , where the latter is embedded via its action on binary cubic forms. We obtain both a numerical multiplicity formula, as well as a minimal system of generators for the geometric realization of the rule.
