The author provides a natural generalization of the algorithms of [\textit{A. Assi} et al., Compos. Math. 104, 107-123 (1996; Zbl 0862.32005)] as well as a collection of examples for modules of type \({\mathcal D}^r/N\), where \(N\) is a submodule of \({\mathcal D}^r\). This family of examples is a first step in the study of the behavior of the slopes under elementary operations over \({\mathcal D}\)-modules (direct sum, syzygies,\dots).NEWLINENEWLINEFor the entire collection see [Zbl 0963.00025].
