Abstract
- This article considers cuspidal curves whose coordinate rings are numerical semigroup algebras. Their rings of differential operators are shown to be cocommutative and conilpotent left Hopf algebroids. If the semigroups are symmetric so that the curves are Gorenstein, they are full Hopf algebroids (admit an antipode).
