The aim of the paper is to study the ring of differential operators \(\mathcal{D}(A(m))\) on the generalized multi-cusp algebra \(A(m)\) where \(m\in \mathbb{N}^n\) (of Krull dimension \(n\)). The algebra \(A(m)\) is singular apart from the single case when \(m=(1, \ldots , 1)\). In this case, the a...
